OK James, and all who sail with him, let me tell ya something Bucko; (the perception of) colour is exactly what you describe, in that what we really see is, a reflection within the visible spectrum of that particular item.
When I stated 'snow is white', it is inferred I was talking about its colour properties and not its intrinsic properties.
Anything outside of that is diving into the realms of philosophy which I self-evdiently was not doing.
If I say that snooker ball is red, the light absorbed by that snooker ball is everything but red and therefore the red wavelength is reflected back to your retina and so, your point is academic mate, sorry James, but you did start it mate
