Chroma. Gray. Blue.

Chroma. Gray. Blue. continues to progress.

As a painting develops, there always comes a point where additional palette-triangles need to be made. That point is reached when I find there are no more existing palette-triangles that fit the section of the painting that is being worked on. There are always unused palette-triangles that can be used in different parts of the same painting, or can be saved for another painting.
