We have already been over this. The point you are still missing is that
while you keep insisting that colors are NOT IN NATURE, you are mistaken.
Light comes in different wavelengths of the elecromagnetic spectrum. "The
full spectrum of the INCOMING RADIATION from an object DETERMINES the
visual appearance of that object ...." -- http://www.yorku.ca/eye/spectru.htm
You know what 'determines' means, don't you, old boy?

Color can exist without eyes to see it?

I do not say that the colors do not come from natural stimulae, only
that without perception of them they would not exist as experiences.
What are colors to those who cannot see?
That we have names for the different colors that we perceive is not a
cnsequence of their wave lengths, since those who do not perceive those
colors have no idea what those names mean.
And the clors that we see are influenced by our interprtretation of
perceptions as well as by the purely physical stimulae.
We 'see' a thing as having the same color under a wide variety of light
conditions, though the actual physical stimulae vary considerably.
Dothings appear to change color througout the day? In fact the light
reflected off, say, grass will differ widely in its spectral analysis
throughout the day from dawn to dusk, but we see it as always the same
color despite such variations.
So that if Simple Septic were right and "color" were purely physical,
we would have to allow that the same color can be different colors and
that different colors can be the same color, depending on conditions.
