Does square enix hate purple?

[ItMe]

Orange and brown exist. Oranges are the various wavelengths of light between red and yellow, and browns are just those wavelengths with lower saturation.

Purple doesn't exist in the sense that there's no pure wavelength of light we can ever associate with it

You're right.
What I was trying to get at is that our eyes only have cones for the colors red, green, and blue.
All of the other colors are our brains making something up to associate with the other wavelengths.
