: This is baaad!

TODO: problem here is that tint as it is is just a nasty hack modyfying Y component and therefore changing RGB coefficients in wrong way, because modifying only Y in that way doesn’t move XYZ point orthogonally to planckian locus. That means it actually changes temperature and thus it lies!
