spaceman says

<<Sorry, Craig, you got this wrong.
Light of different colors is light of different frequencies.
The frequency of light emitted by some atom, does, in fact, 
exist independent of our brains. It's called hertz.
 
Using your argument, only the word "color" is dependent upon
out brains to interpret it (as you point out below).>>


That's wrong. Wavelength is wavelength, color is color. There is a relation
but it is not nearly as close as you seem to think. Color is definitely
about perception. You can perceive color even though no light of the
relevant wavelength is present. the Land two color experiments (and many
other similar experiments) show this conclusively.
