Thanks PE,

Certainly, the film must capture the 3 color sensations, red, green and blue; but their end color is where I'm saying there is room for "slop", or flat out "false color", as long as there is a way to separate them optically from one another.

The blue, red, IR was just an example, something that I read in relation to Dr. Bela Gaspar, but honestly I don't know what the final Gasparcolor product was like.
