Libraries for choosing colors?

Question

Are there any open source libraries for programmatically selecting and evaluating color set compatibility using color theory ?

It would be very useful to be able to choose color palettes based on simple rules of color harmony, such as free, similar, process and notebook colors.

Answer 1

I just found this: Harmony Theory and Mathematics .

Also interesting is the rest of the EasyRGB site, which will explain how to make RGB for HSV, etc.

While this is not source code, these are formulas for calculating values.
