I don't really post here very often, but I have been working on an idea that has been knocking around in my head for a while - a color wheel, to be used as a universal painting palette, that represents 3 dimensional color (HSV) in 2d. I would like to get people's feedback on it's practicality and whether or not it is of any use, and I am certainly open to suggestions. The idea is a single image that allows for single click selection of as many colors as possible. Let me know what you guys think. If its use isn't self explanatory and you would like a deeper explanation of its implementation I'd be happy to oblige.
