Live

Requesting review of updated Color module.  The goal was to create a Class that represents a Color, not an expression of a Color - so any component value (red, blue, hue, saturation, lighntess, brightness, etc) can be set and all others will be updated automatically (thus the "Live" topic branch name).  Specs/docs.html has more information.  Specs/demo.html has a small proof-of-concept.
