A Java implementation of the Kubelka-Munk Theory of Reflectance for mixing RGB colors. This implementation uses a simplified version of the Kubelka-Munk model that assumes all colors have the same concentration when blending and that all colors are opaque.

WARNING: Currently this project seems to have some issues with the implementation and some color mixes do not result in the expected colors. Unfortunately I do not currently have the time or insight to fix the issue(s). Pull requests very welcome.

The ultimate goal of this project is to have a intuitive (subtractive color model) yet accurate color mixing function of the form:

Color mix(Color a, Color b)

The KMColorUtils class contains two mix methods for conveniently mixing java.awt.Color objects.

public static Color mix(Color colorA, Color colorB);

public static Color mix(Color... colors);
