Your definition of color is based only on human perception? Is purple a color for a mantis shrimp?
Edit: I guess not in a pure sense because it’s still two wavelengths of light. Perhaps a mantis shrimp can detect a totally different wavelength and sees it as “purple” or something.
Now I’m thinking about how we don’t know how other humans interpret colors. Like what I see as red, you may see as blue. Ugh.
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”
