this comes from
http://en.wikipedia.org/wiki/List_of_colors_(compact)
with some modifications to the names to let them work as variable names. there's about 900+ named colors.
usage:
#include "ofxNamedColors.h"
ofSetColor(ofxNamedColors::alloyOrange);
ofSetColor(ofxNamedColors::classicRose);
everything is static inside the class. you can also use some helper functions for iterating through the whole list
setupColorMap(); // allocates the static map of name to ofColor and populated a vector of color/name mappings
ofxNamedColors::colorNames // the vector of mappings.
etc.
the example shows you all the colors:
as well as lets you sort them by hue, which can be useful:
