  Just as a backgrounder, there's a company called
Color Kinetics that
 owns the patent for mixing R, G, and B light from LED's. I was
 briefly targeted by the company in the 90's for suggesting on Usenet
 that the same could be done without paying them royalties. I know
 that most legal action is heavy-handed, but these guys are big
 hitters and will come down hard on anyone who suggests that mixing
 these colors can be done without paying them royalties.       
They musty have been trying it on. There's surely no way they
can do anything to stop you discussing how to avoid their patent.
Nothing to stop them trying to scare you off though.
