otoh i had my brain broken a bit when i learned this year (how did i not know, or at least notice the impossible 2d'ness of color charts?) that purple does not have a wavelength but is our brains made-up representation of "a color midway between red and blue which is not green", and while a computer can also do that for us it drives home how fake our idea of colors are.
