The existance of green stars or green space lights is very important because it makes a strong case for blue red green as universals and it puts yellow in a stranger position.

We are talking about everything from atoms to stars to the light received in the back of our heads to shafts of light in the late afternoon.  We may very well be these colors across our own bodies.  The night sky may be a field of hidden colors.  It is like saying these colors make up everything somehow.  Or not?  Is there anything to this?
