This takes me back to what I did as a profession. I had a printing business for about 35 years.
There is a system of color charts for printers, called Pantone colors. You can mix hundreds or even thousands of colors on demand. When I was in the art supply shop, I found a set of artist colors that are the basic primary 4 colors ( black, magenta, cyan, & yellow) that are used for process colors, (full color), these are transparent colors, when they are over lapped on a printing press they form what ever color you wish.
Let me explain a little further about how process color (full color} is done in the printing business.
A photograph is made into a halftone, which is a series of dots of different size that forms the overall picture. This is photographly transferred to a metal plate for the press. The process colors are transparent so you have overlapping dots that form the different colors, like in art where you use a wash of other colors to create what you want.
This will probably confuse everyone. But I am using my pantone color charts to mix my artist colors.
If anyone has any other questions let me know and I can explain further
