    Definition I’m using is any color that can be expressed as a single wavelength of light. Purple cannot be, since it’s actually two wavelengths simultaneously.

      Perceiving it as a color seems more practical though. It’s not like we look at “red” and think “ah yes, a single wavelength of light”
