When I said "evoked" I was relating the physical definition to the physiological aspect which you are focusing on.I haven't changed definitions. I have yet to see one. I repeat, saying it is evoked is not defining it. If you define red as light in a set range of wavelengths is one way to do it. But then red = light between X and Y. Anything outside that set is not red and anything inside is. Whether anyone ever perceives that light is irrelevant. In which case, red is evoked by nothing, it just is.
Again as far as defining it, I was repeating the physical definition. If you want to go into the full spectral complexity of "red", the discussion turns to hue, saturation and intensity and the ambiguity of different evaluations by different people. That falls under the realm of physiology, not philosophy.
