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)
I called black a real color because if we see black, we know for certain there’s actually no light.
And yes I know all that other stuff.
But how can you tell when you see cyan, if it’s actually cyan wavelength or a combination of two completely separate wavelengths that your brain just averages into ‘light blue’ or whatever?
yea I know thats why I called it a slippery slope, because if you know for certain that there’s only one wavelength in the scene then you could tell its cyan, but if it could be any spectrum then you would have no idea
