Saturation : the intensity of the color. Ranges from 0 to 100%
Brightness (or Value) : the brightness of the color. Ranges from 0 to 100%
HSV to RGB conversion formula
When 0 ≤ H < 360, 0 ≤ S ≤ 1 and 0 ≤ V ≤ 1:
C = V × S
X = C × (1 - |(H / 60°) mod 2 - 1|)
m = V - C
(R,G,B) = ((R'+m)×255, (G'+m)×255, (B'+m)×255)
