    Similarly, I think I’ve read somewhere that pink isn’t in the color spectrum. Or was it magenta?

      A lot of colors, like those, as well as gold, aren’t on the spectrum of visible light either.

        Gold is – it’s an orangeish yellow. I think what you’re meaning is that when people say “gold”, they usually are referring to the material properties of the metal as well. But the actual color does have a spectral hue. Magenta on the other hand, (including shades of pink that fall under magenta) is not a spectral color, and is just how our brain interprets the combination of signals from our red and blue cones.

          Right. If you took a picture of a piece of gold and either sampled a point or blurred it together to one color, it wouldn’t look like gold any more.

        I’ve always wondered why no one ever seems to mention that there’s no such thing as brown light.
