It’s Warm In There! – Lessons on Color Temperature

One sunny, breezy day over twenty five years ago, I was painting boats at a picturesque harbor on the Maine coast with my teacher and mentor Ned Jacob. There is some sort of special hell reserved for artists painting boats, especially boats that are moving. bobbing up and down and generally not staying still! But, on this day, it wasn’t drawing that had me totally flummoxed. I was painting a white fishing boat moored nearby and felt I had a pretty good drawing of the structure. But, as I tried to paint the interior of the cabin, which was in shadow, I could not make it look right. It looked like a flat piece of paint rather than an area receding away from the outside of the boat. I had a nice pile of grey paint that looked like the right value for the shadow. Ned looked over my shoulder and said “It’s warm in there.” Then he picked up a speck of cad orange with his brush, dropped it in my grey and applied it to the canvas in one deft stroke. It went back, it had “air”, it was warm in there! It was my first lesson in color temperature and I never forgot it.

Color temperature seems like it ought to be a really easy concept, but in my experience it is both hard to understand and, for the inexperienced, even harder to see and therefore to paint. One thing I learned from Ned was where to look for it- where and how to identify places that might hold a color temperature change. Once I knew where to look, then I saw it everywhere!

It was several years later when I read that well known adage “break temperature not value” in Birge Harrison’s book Landscape Painting. It took a while to understand how color temperature and value can be used together to create not only solidity of forms with an economy of values, but will also be the most effective combination to produce the illusion of light and atmosphere in the landscape. Although you can depict it with well organized values only (convert master paintings to greyscale if you doubt that!), the combination of an economical value structure with strategic color temperature shifts will positively make a painting sing!

Here is a painting by American artist Clark Hulings (1922-2011) that illustrates this point. Notice the color of the wall in shadow. The cooler color above is influenced by the sky while the warmer color in the lower part of the wall partakes of the reflected color from the ground. Both the warm and cool notes within the shadow are different temperatures, but the same value!

In the next post, we’ll explore other examples of where to look for color temperature changes. Stay tuned!

The Three Uses of Value

As we know, when we refer to value we are speaking about how light or dark a shape or form, or part of a shape or form are. Generally when we refer to value we are speaking comparatively, that is, how light or dark something is compared to something else. However, by using a value scale we can begin to assign specific values to things and to talk about value in a more precise way.

p.txt-4 2

Values serve three functions in the art of landscape painting. First, using the correct value or range of values can help us create the illusion of outdoor space, air, atmosphere, and forms receding into the picture plane and to generally create a convincing depiction of outdoor Nature. This is Carlson’s Theory of Angles and aerial perspective.

Carlson Illustration

Secondly, values can be used to create the illusion of three dimensions in specific forms like tree trunks or rocks or any other objects we might find in the landscape. This is called modeling, shading or “turning form”.

p.txt-3

Third, values are used to create the overall structure of the painting, organizing them in such a way as to create a pleasing design. This is composition.

Morning Light 2430 72 greyscale_edited-1 Morning Light 2430 72 dpi

Of course, all these functions are interrelated. When we choose a certain value scheme to depict a sunny day for example, we are also making choices about how the values we use will help us show the solidity of forms and create a pleasing design. But, for purposes of study, it is useful to separate these functions and study them independently until they are all fully understood and can be applied together.

P.S.  Want to build a solid foundation for your landscape paintings?  In our online class Understanding Values in the Landscape  we study in depth Carlson’s Theory of Angles, atmospheric perspective and how each affects the values in every part of the landscape.  Then we take a deep dive into the all important skill of how to “key” a landscape , using a particular value range  to depict different times of day and lighting conditions.

Let it Snow!

Many of us are facing bitter winter weather just now. So, it seemed an appropriate time to talk about…painting snow!

Two of the main concepts to keep in mind when painting snow are value and color temperature. When painting a light, highly reflective surface like snow we are hampered by the value limitations of our materials. Our white paint is the lightest light we can muster. In order to effectively represent snow and its surroundings, we must darken its value just a little, as well as the other planes in the landscape likes trees, hills and sky.

Because of its reflective surface, the color of snow is affected by the colors around it, most particularly the sky. That is why on a bright sunny day when the ground is covered with snow, you will see those intense blue shadows. That’s the zenith of the sky reflecting into the shadows. Recognizing the source of that color and maximizing it helps to describe the snow. In this painting you can see contemporary American landscape painter Stapleton Kearns doing just that. He has used a warm white for the sunlit portion of the snow and cooler whites to depict the planes turning from the light and the shadows. This is a great example of how one might model the snow on a sunny day.  Notice too how the value of the sky has been lowered just a bit and the rest of the scene brought into that range as well. The warm notes in the foreground logs provide a temperature counterpoint to the overall cool cast of the painting. Finding opportunities to include a warm note in a snow painting adds variety and richness to the snow filled world.

But, often when we paint snow, it’s not a sunny day. Here is a lovely tonal homage to snow by American painter John Carlson American ,1875-1947), author of Carlson’s Guide to Landscape Painting. The color of the snow reflects the muted sky color, and the close values of grey, brown and violet in the near and distant trees evoke a quiet winter day in the woods. Subtle warm notes in the trees and plants sticking out of the snow provide the needed variety in temperature.

Here’s one of my favorite snow paintings by Frederick Mulhaupt (American, 1871-1938 ). Mulhaupt has used value masterfully here. The counterchange between the light tree trunks and darker confers behind is echoed by the small triangle of dark water on the left. The violet sky is darker than the snow which helps to set it off and appear luminous. Subtle temperature and value changes within the snow describe the ground plane underneath, and the dark bits of earth peaking through lead the eye to the central arrangement of trees. The remaining foliage on the trees provides a warm counterpoint against the violet sky. Quite an orchestration!

Mulhapt snow

In this painting, I wanted to evoke the memory of a day in snow filled woods. The quiet muffled quality of sound, the intimacy of the deep woods, and my part in it were all on my mind. I used subtle value and temperature changes to depict the foreground snow and describe how it began to pile up on top of grasses, plants and tree trunks. Warm notes in the foreground provided a counterpoint to the violets, greys and browns.

Finally, here is a painting by Marc Dalessio (American, contemporary) which he posted on his blog. He helpfully included a photo of the scene he was painting. This provides a great example of how he has manipulated value and temperature to create an effective design. Note how the snow value has been lowered and its temperature cast shifted to a very light blue green. Notice also the warm note of pink on the edge of the shadow underneath the main tree on the right and a similar note on the other side of the road. He has also darkened the value of the trees in the distance just slightly and the main tree as well, providing needed darker notes (along with the tire tracks).

Orchestration of value and color temperature is the key to success in snow paintings. So, go out and paint some snow!

Learn to Key Your Landscape

Landscape painters need to have a good understanding of the importance of value in successfully depicting the landscape on a two dimensional surface. In order to have our painting ‘read’, that is to show the planes of the landscape as well as its depth, atmosphere and scale, proper values are essential. As we’ve previously written, Carlson’s Theory of Angles is a great place to start as an overarching concept for understanding values in the landscape. But, it is only a starting point!

Another layer of complexity is added when we think about how to depict the varying atmospheric conditions, times of day and effects of light that we observe in Nature. Again, values are the key to success here. And, we often refer to this process as ‘keying’ the landscape.

For example, in order to key your landscape painting to depict a sunny day as opposed to an overcast day, you must learn to shift the value range up or down the value scale as well as understand the proper value steps between the light and shadowed parts of each plane in the landscape. It sounds complicated, but with careful observation and application of some basic concepts, this knowledge will allow you to paint what you see more accurately and also change the key of your landscape when painting from memory or imagination. This combination of observation + knowledge, gives you the ability to paint any light effect or time of day. It also gives you the ability to convincingly change the time of day or light effect from what you see in nature or from what is depicted in your reference material. This is a key skill in landscape painting (pun intended).

Here are a couple of examples. In this painting by Willard Metcalf (American, 1858-1925) we see a beautiful effect of bright sunlight.

Willard Metcalf Giverny

When we convert the painting to greyscale, we can see that there is a wide range of values from light to dark. Also, the lights and darks within each plane are several steps apart. Look at the grass (ground plane) for example and notice that there is a 2-3 step difference in value from light to shadow.

Willard Metcalf Giverny greyscale

In this painting by  Claude Monet we are treated to a beautiful effect of low light and an overcast sky. The colors are more muted and the values in all planes of the landscape (sky, groundplane, uprights, slanted) are closer together.

Screen Shot 2017-12-25 at 1.29.12 PM

The greyscale of this painting shows a close value range and a shift toward the darker end of the value scale. The shifts between light and dark in the foreground are less than than a step apart, and the white sails of the boat are a step or more darker than the lightest value on the scale.

By understanding both the value range and the steps between light and shadow found in each light effect or time of day, we can learn to key our landscapes effectively.

Break Temperature Not Value

Nature is, as John F. Carlson said, an overloaded property room, and often as landscape painters we find it challenging to create a painting that has a sense of unity, as opposed to being a composite of parts.

There are many “picture-making” strategies for simplifying and unifying nature into a work of art, such as looking for “big shapes” and creating a coherent range of values.

Carlson admonishes us not to copy Nature “tone for tone” i.e., value for value,  and to keep the simplicity of the large masses. But it is Birge Harrison, the author of  Landscape Painting (1909) and Carlson’s teacher, who shows us the way to do that: break temperature not value.  By using temperature shifts of the same value, rather than value changes, we can add variety and interest to the large shapes. By doing this, those big shapes are not broken up and the large masses and the painting retain a sense of unity.

The technique can be done in a number of ways. Harrison describes one way in which the artist creates a warm underpainting, essentially a full value study and the paints over it, matching tone for tone but using cooler colors in the overprinted layer. Allowing some of the underpainting to show through creates vibration.

Another method  would be to paint opaquely and juxtapose warm and cool touches in the same mass.

Here is an example by William Langson Lathrop (1859-1938), a well known painter, etcher and draftsman and one of the founders of the New Hope School of Painting. In the foreground of this painting there are relatively few value changes in the ground plane yet there is a great deal of variety accomplished by the use of warm and cool colors of the same or very close value.

Screen Shot 2017-10-22 at 3.07.13 PM

Here is an example by Peder Mork Monsted (  Danish, 1859-1941). If you squint you can see the light and shadow parts of the snow hold together, but when you really look into them you can see numerous temperature changes which he uses to add variety AND  to suggest information. The warm and cool notes on the snow bank to the right of the road is a great example of that.

Screen Shot 2017-10-23 at 8.09.50 AM

In this second example, we see contemporary landscape painter Clyde Aspevig doing the same thing in the shadow area of the snow and in the sky.

Screen Shot 2017-10-23 at 8.10.01 AM

Here is another example by contemporary landscape painter Marc Dalessio. The street is depicted with both warm and cool colors of the same value creating lively vibration and interest without breaking up the mass.

Screen Shot 2017-10-22 at 3.11.28 PM

In all of these examples there are just a few values shifts, but lots of temperature changes.

So, to create variety AND unity: break temperature not value!

Deconstructing Carlson

As we all know, John F. Carlson (1875-1947) is the author of the ‘bible’ of landscape painting, Carlson’s Guide to Landscape Painting. As might be expected, a study of Carlson’s work can be extremely enlightening!

This is one of my favorite Carlson paintings and a great example of his mature style and larger finished works. I used Photoshop to reduce the number of values for the purpose of this exercise.

In an initial glance at this work, we are struck by the massive solid forms of the trees, the subtle but beautiful color harmony. But how to simplify all this forest interior?

screen-shot-2016-11-06-at-8-52-48-am
John Carlson

Here is the Notan ( 2 values) version. As we can see, this painting hangs together beautifully as an abstract design, with the darks linked and interesting shapes and negative shapes.

carlson-notan
Notan

In this 4 value version we can see how the foreground trees are really part of a large shape which is cut into by the shape of the trees/hill behind and the sky and ground. If you flick your eyes back and forth from the notan version to this one you can see this better. So, while initially we see lots of individual trees, by simplifying, we can see that foreground trees are one shape and background trees/hill another. With the sky and ground shapes, we essentially have 4 shapes. We can also see how important the simplification of the values is to this ability to reduce the number of shapes and to the overall strength of the design.

carlson-4-values
4 Values

In this six value version, although the main shapes are further described with additional values (and accordingly the value scheme gets closer and has less contrast), the main shapes still hold together.

carlson-6-values
6 Values

Strikingly, in this final image which is a greyscale version of the painting, there isn’t all that much difference between it and the 6 value version. The differences mainly have to do with how the use of more values pulls the value range closer together, but the main shapes we identified previously still hold together very well.

carlson-greyscale
Greyscale

This is an important lesson and goes hand in hand with Carlson’s admonition not to copy ‘tone for tone’. Doing so will break up the large masses, and the painting will lose the strength of its underlying architecture of big shapes.

Four Value Studies and Notan

This week in the Composition class, we have been working on thumbnail sketches, which employ simplified shapes and values to help us explore design possibilities. Thumbs can and should become the main tool we use to both learn to compose and to explore motifs for paintings.  The class worked on applying certain design principles to the task of creating thumbnail sketches. In the coming week, we will explore using four and two value studies to further sharpen our design skills.

Notan is a Japanese word for light-dark, and consists of a two value arrangement of shapes.  It can be used to define and simplify shape and value patterns. Notan (two values) and  four value designs are not based on how we actually see the world; they are constructs that we can use to see and strengthen value patterns.  Both Notan as well as the four value studies require us to make decisions about whether mid-tones will be grouped with dark or light. This allows for a more flexible approach to thinking about design.

It’s hard to overstate the “aha!” moment that arrives when students first begin to grasp the power of using a limited set of values to compose. Here are a few examples of master works.

Here is George Inness’ Sunset in Georgia, a work which immediately catches your eye with its rich color. But the real strength of this work lies in its value pattern.

Onness Georgia Sunset

Here I have reduced it to four values. You can see how Inness has connected all his darks to create a tunnel design. This did not happen because he saw it that way in Nature , but rather because he designed it that way. Remember, composition is something you impose on Nature.

Inness Georgia Sunset 4 values

Here is a painting by the 19th c. Russian landscape painter Ivan Shishkin.

Shishkin forest dusk

 

In this example I have converted the design to four values. Again, note how the darks are all linked. This is a key factor in creating strong value structures for your paintings. Although there is lots of information in this painting and very close values, with small incremental value shifts, its overall structure and design can be reduced to just a few values.

Shishkin forest dusk 4 values

In this example I have reduced the values to two- Notan. Again the darks are linked. Note that the sky forms a shape as well as the other elements of the scene.

Shishkin forest dusk notan 1

Here is an even more simple Notan.

Shishkin forest dusk notan 2

We can use these same ideas to help refine our own work. The first thumb is about 2 x 3″.

DMP thumb 2

Here I have reduced it to four values and added a lighter value in the distance, Although I liked the right hand side,  the darks on the left were not connected sufficiently.

DMP thumb 2 4 values

Pushing the values to the darker end of the scale.

DMP thumb 2 4 values 2

A Notan to explore how to more effectively link the darks.

DMP thumb 2 notan

 

Working with simplified shapes and reduced values can help to refine out motifs. No amount of color, bravura brushstrokes or detail will rescue a weak design. Working with thumbnail sketches and reduced values teaches us to create a solid structure for our work.

 

P.S. We have a great lineup of online classes coming up including our very popular class on Understanding Values in the Landscape, and a new painting class called The Strong Start. Join us! For those interested in a comprehensive program of training for landscape we are accepting students into the Atelier programs for the January trimester.

 

 

Drawing and Painting Foliage- Value Maps and Squinting

John Constable, one of England’s and the world’s most revered landscape painters, spent his career making drawings and painted studies from which he then worked up his famous “six footers”. Constable’s work was enormously influential in France with the Barbizon school of landscape painters, and eventually the Impressionists.

Here is a typical drawing of his and it is instructive for us when learning to see and paint masses of foliage.  As you will note, Constable has carefully delineated the values within the foliage masses and used lights, midtones and darks to create form. These areas are not randomly created- they are based on the architecture of the tree. But, you will often have to “mass” these areas of value to create a solid look to your tree. In most cases, there will be many more value changes than you will want to describe. To do so will break up the volume of the form too much.

 Here is another drawing by William Trost Richards (American, 1833-1905 ) showing the same technique.
Wm. Trost Richards

If you click on this for a larger view, you will note the beautifully organized areas of value which help create the illusion of volume in the foliage masses.

So, squint down and look for the large value areas. To help you accomplish this, do a little sketch to map out those areas before you start your drawing or painting. This will help you see them as well as design them in a pleasing way. Here is an example of a value map. This kind of sketch can really help organize your values before you start.

Screen Shot 2015-08-27 at 6.00.29 PM

Here is another slightly more finished “value map”. As you can see, I have massed the lights and darks and also used mid tones to describe the planes of the foliage. When you look at foliage try to see those planes- where the light strikes the mass, where it turns away from the light, and where it is in shadow. If you squint you can see this clearly. Then the challenge is to “mass” those areas.

Screen Shot 2015-08-27 at 6.00.51 PM

Go outside and do a lot of observing of foliage until you begin to see the patterns. Do some simple value maps to gain experience with the idea of massing. Notice the direction of the light and how that affects the values you see. Here are two more simple “value map” drawings, the first showing top lighting and the second depicting lighting from the left top side of the tree. In both simplified drawings, I have identified the lights, mid tones and shadow areas by squinting down and also by simplifying those areas. In Nature, those values will not always be clearly organized. If you try to copy them as you see them, the result will look spotty and break up the solidity of your form. So learning to squint and simplify is the key to success.

Lessons From a Walk

Last summer, while out for my usual early morning walk, I noticed this big foliage mass of a tree which hangs over our road. The thing that struck me about it was that it perfectly demonstrated a couple of points that come up when painting trees, and really anything in Nature. I took a picture of it hoping that the values and colors wouldn’t get too distorted and that I might be able to use it as an example. Luckily in this case, the photo shows the points I want to make pretty well.  Click to enlarge.

lesson from a walk photo

First, as we talked about in this post, often the mid tones will be the most chromatic, that is have the most intense color. This is because the color is not as washed out by light as the lights are, and isn’t dulled as much as the shadow areas are. I think if you click on this photo you can see pretty clearly how the mid tones have a more intense green color than either the lights or the shadows.

Secondly, you can also see that the top planes of the foliage in the back right side are cooled by the light from the sky.

Third, the light struck parts of the tree facing to the left are not all the same. Those closest to the light- that is, the area on the top left  are the lightest and warmest, while those more in the middle of the tree and farther away (on the right) while still struck by the light are not as light or warm.  This is something that is often noted in figure drawing, but seldom discussed in landscape painting. In fairness, it is a lot more obvious on the figure because the light source is closer to the model and both are closer to the viewer, but the idea is the same.

Fourth, I think you can see that the interior shadows are warmer than the shadowed areas on the outside of the foliage mass, which we discussed in this post.

lesson from a walk photo desat

And finally, this greyscale version of the photo demonstrates how the values of the upright planes on a bright sunny day might well be darker than you think. The lights come in at about value 5. That warm green color fools our eye into thinking those lights are much lighter. But, if we paint them too light, of course, they are “out of value” and stick out like a sore thumb!
