Jeg er ved at skrive et par funktioner der sammenligner og tester farver.
Den gamle algoritmen for lysstyrke var nem nok at implementere. Jeg kan
sagtens gennesnskue den nye, men der er et symbol jeg ikke kan få på plads
nemlig "^2.2".

Hvilken operation skal jeg udføre for gamma korrektion?

(L1+.05) / (L2+.05) where L is luminosity and is defined as .2126*R +
..7152*G + .0722B using linearized R, G, and B values. Linearized R (for
example) = (R/FS)^2.2 where FS is full scale value (255 for 8 bit color
channels). L1 is the higher value (of text or background) and L2 is the
lower value.
