There is 1 other problem that is more important than human recognition.
It's called the Mach Effect (I believe)   This effect is the eyes ability
to differentiate differences in color when these colors are right next
to each other.  Normally the eye can't tell the differece between shade
1 and shade 2 of green.  However, make these 2 shades butted up 
against each other and suddenly the human can see the difference.
There are some computer graphics specialists that can distinguish
over 200 colors of green when the mach effect kicks in.

I assume this artifact came out to keep people from being eaten by 
leaf green saber toothed tigers in a forest :-)
