Beginning the Color Underpainting
My limited palette consists Naples yellow dark, cadmium yellow light, cadmium orange, cadmium red light, permanent madder deep ( a more permanent color than alizarin crimson), burnt sienna, ultramarine blue, thalo blue, thalo green, and ivory black.
So I used a lot of thalo blue and thalo green. I have learned to be judicious with these powerful colors, but they have a wonderful tinting strength. Many times I dilute the thalo colors with pinks and reds.
