Not every class requires a full palette so before each class, students will receive a Materials List and Reading List which are specific for that class.
The palette is divided into two sections-the opaque colors  and the transparent or semi-transparent colors, although there is some cross over (e.g. ivory black and ultramarine are transparent).  Colors that are specifically formulated as transparent are preferred for glazing because they retain their intensity better than opaque colors which are made transparent by diluting with medium.  Gamblin has developed a line of modern mineral based pigments which gives the contemporary artist a much broader range of colors to work with.
The Vasari Shale is the pigment used for transparent underpaintings, sometimes mixed with Transparent Earth Yellow (TEY) made by Gamblin. It is also the workhorse dark on the palette. Vasari paints are expensive so you may or may not want to purchase them (but they are excellent quality). A less expensive alternative to Shale is a mixture of sap green and alizarin crimson, or ultramarine and burnt sienna.
Liquin is the medium used for general painting as well as glazing. Oleogel by Natural Pigments is another choice. Most any painting medium that helps increase paint flow will work. Turp or Gamsol will not ( Gamsol-  only for cleaning brushes).  Galkyd Gel is used to retain brushstrokes and create a glaze impasto.
