I'm kinda curious how your colour theory works, because it reminds of the fact that Brian Stelfreeze has his own colour theory as well. But that makes no sense. There should only be ONE Universal colour science, not three...
Well, Brian is a color master. He schooled me in the ways of color many moons ago. I don't have the patience to do it exactly the way you’re supposed too, but I know enough now to fudge.
What you’re seeing isn't different color theories, your seeing applied theory. Just like there are certain methods to traditional inking, but every inker develops their own way of using it, same with color or anything really. It's just personnel taste.
I'm criticized a lot for being too monochromatic, but it's the way I see things. I look at coloring as lighting. Some people don't seem to understand that yellow or green or blue isn't the color you think it is. It changes constantly due to light. In warm light, cool light, black light, what ever light, that color will change slightly. It's called color balancing. There's even a tool for it in Photoshop.
