Well, color can, of course, be arrived at by various means by color mixing, amounts, etc. And certainly practice plays a role. Maybe I am breaking-down color, as you said. Which is a good way to put it.
I guess what I meant was-the ability to describe complex colors with words and/or envision them in the mind before actually seeing the mixtures play out in paint. Like the way someone telling someone how to cook something might say add a dash of salt, and a 1/4th cup of flour, etc, but not actually showing the person.
But maybe it is all the result of practice. I've been drawing/painting all my life. I didn't think that it was necessarily a special skill. It's always hard to put visual thinking in the terms of written language.
You're right, however, it is fun. ![Smile :)](./images/smilies/icon_smile.gif)
