The simplest color_map possible (color_map[0 rgb 1][1 rgb 0]) actualy have an 
"infinite" number of distinct values. That is, every real values comprised 
between 0 and 1. This number is reduced in a computer by the limitation of the 
binary floating point encoding, but still largely bigger than 65535.
