Color::RGB and Color::CMYK were originally developed for the Ruby PDF project and PDF::Writer and represent wholly unique code.

Color::Palette was developed based on techniques described by Andy "Malarkey" Clarke, implemented in JavaScript by Steve G. Chipman at SlayerOffice and by Patrick Fitzgerald of BarelyFitz in PHP.
