- Why are most metals gray/silver? 6 answers
Or any other silver surface? Perfect silver "colour" just seems to be "reflecting gray", so something that absorbs all wavelengths by the same fraction and reflects everything else specularly. When I scratch it, it gets gray.
So a mirrors are gray and specular reflectors and therefore the colour we commonly call silver is, also, simply gray and specular. Is that correct or am I heading in the wrong direction here?
