RGB to HSL conversion formula

The R,G,B values are divided by 255 to change the range from 0..255 to 0..1:

R' = R/255

G' = G/255

B' = B/255

Cmax = max(R', G', B')

Cmin = min(R', G', B')

Δ = Cmax - Cmin

 

Hue calculation:

 

Saturation calculation:

 

Lightness calculation:

L = (Cmax + Cmin) / 2
