Vertex data can be of any range for x,y,z,w, but color and texcoods range from 0..1.
Think of out-of-gamut colours as just like out-of-screen vertices.
Have the results of cramming one data type into the other even been proven effective at all?
What is what you call effective? Cramming is a delightful activity. It's also called databending by some people. To me, it's just everyday business, so i don't even bother calling it names.
Personally, when I want to convert texcoords to colours i just multiply them by a matrix like:
1 0.5 0 0 0.5 1
Which causes y's to be mapped to orange and and x's to some bluish cyan. (my "texcoords" have the y before the x; i'm not doing this with GEM)
