RGB is not a perceptual color spec. RGB specifies pixel color values
to be used in CRT or LCD monitors. How it is eventually perceived  
depends on monitor
manufacture, user adjustments, monitor age, room temperature, how long  
the monitor has been turned on, lighting, the color of items near the  
monitor, and other variables.
