THE HUMAN EYE'S LIGHT SENSITIVE CELLS (PRIMARY CONES) ABSORB PRIMARY COLORS OF RED.GREEN AND BLUE THAT MANIFEST THROUGH DIFFERENT WAVE LENGTHS OF LIGHT.

 MIXTURES OF THOSE PRIMARY COLORS THEN GIVE US ALL THE MANY HUES AND SHADES OF COLORS THAT ENRICH OUR WORLD.

 SOME SOURCES SAY MILLIONS OF POTENTIAL COLORS EXIST,  ALTHOUGH THE HUMAN EYE IS UNABLE TO DISTINGUISH BETWEEN ALL OF THEM.
