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)
Try wrapping your head around colors used in taxonomic keys for a bit.
Can we have a picture with correct white balance? So we can actually see the colors?
It's a picture I found on Google, I messed with the balance and updated my post so it's somewhat better.
Thanks mate!
