I don’t knit with color very much, just because of limitations on time and money, but I absolutely adore playing with color palettes and creating fair isle designs. Just recently, I came across an old coloring book of mine that is full of snowflake/fractal-type designs, and it’s specifically intended for artists to play with colors! I’ve been having fun coming up with all kinds of neat color combinations, and actually coloring in the pictures that I thought were too pretty to touch when I was a kid. Get on amazon.com and do a search for “designs for coloring” and you’ll come up with tons of adult coloring books – they’re really fun and helpful!
