my reasoning: the actual colors we can see -> the wavelengths that we can extrapolate to -> basically extrapolated wavelengths plus an 'unpure-ness' factor -> not even real wavelengths (ok well king blue and maybe lavender if I'm being generous could be)
White is.. impure? And the disrespect for minerals... No no no this won't do at all, I am coming over and burning all of your pudding (a fitting punishment)
