"After a such a long and articulated explanation that it is your brain that, after a long evolution, translates wavelengths as "color", you still don't understand that color does not exist outside our brains."
NO, YOU are the only one who didn't understand. our brains CANNOT "magically" create the appearance of color, stop insisting in this woo woo, because this is obviously bullshit.
And evolution has NOTHING to do with it. If this were true, distant planets (which has nothing to do with us) would never have any 'color', chameleons would never change color, etc, etc..
Any photographer, even a pointer-shooter, understands the differences between perceived and "objective" (recorded on film or CCDs) color. If we want to follow your retarded logic through to conclusion, there is no light, nor any reality, because all is perception. Which is clearly bogus.
And the colorfull case of brain achromatopsia proved that all colors are objective, clearly proving your idea to be wrong.
