I had the same problems with searching for Cyan, Magenta, Yellow. There are standards for colors ( like RAL ) but the filament vendors don't provide such information.
IMHO, CMY colors are better suited for color mixing, although all color wheels also mention Black ( CMYB ), which isn't possible with the diamond.
