Boy do I feel dumb. Additive vs. Subtractive colors. Ignore the previous
articles formula, I was drugged, being held hostage, tired, possessed...
In a prefect world (prefect ink, 255 is full on, 0 is full off):
RGB --> CYM
C = 255 - R Y = 255 - B M = 255 - G
CYM --> CYMB
Take the least component of CYM, and make it B. Subtract
B from CYM.
In the real world there is correction for organic dyes, but as it is
getting late I think best to stop before I have to post more tomorrow.
