When mixing colors for skies we concern ourselves with the three attributes of color: value, temperature and chroma. As we know from Carlson’s Theory of Angles, the sky will generally be the lightest value in the landscape–a range of values actually, as the value of the sky grades from lightest at the horizon to darkest at the zenith. There is also a horizontal gradation–lightest near the source of the light and darker as the distance from the light increases. There is also a gradation of hue (color) from horizon to zenith.
In this video, I discuss how all of this affects the choices we make when mixing blues for skies.
