Some math to help you out:

- Can you add a level that is missing like oil paint pigments? ceramic glaze colors? musical pitch? gestures? What are some of the problems of mixing non-screen based color systems with?
- Basic is fine, but think about layout/usage… do you want to pick up a color in a jpeg, from a video camera, find color harmonies/ see relationships? What about color is important to you?

Options
- If you don’t feel up to writing your own software program yet, how about building a template for a cross-medium cheat sheet for the colors you want to use?
- How about a personal color wheel? http://handprint.com/HP/WCL/color7.html is an example of a water color oriented wheel.
