RGB vs CYM limited palette

 To form a limited painting palette, we often use 3 primary colors. This experiment demonstrates the different mixing power of using RGB vs. CYM. For RGB primaries, I used cadmium red light, cadmium green, and ultramarine blue. On the color wheel, we can see the color gamut is rather small, means the colors can be mixed by the 3 selected primaries are rather limited. For CYM primaries, I used quinacridone magenta, cadmium yellow deep, and cobalt teal. on the contrary, we can see the color gamut is significant large, the 3 selected colors can mix much more colors than the RGB case. It is so obvious we can see the secondary colors mixed by RGB are quite dull (low chroma), while the secondary produced by  CYM are much more intense (higher chroma). Therefore, we conclude the CYM forms the best limited palette, while the RGB is not a so good choice for a limited palette.
