A spread of color!

This is a page of extended two color charts for four of the colors in my 24 color palette. I mix the one color with the other 23 to see what range of colors can be created. Here the four main colors are Cobalt Violet (Winsor & Newton), Bright Violet (Holbein), French Ultramarine (Winsor & Newton), and Cobalt Blue (Winsor and Newton).
