How is hue calculated?

To calculate Hue from Red, Green and Blue, in degrees:

1. First identify the Red, Green and Blue values (0 to 1, typically R/255, G/255 and B/255).
2. Identify the maximum (max) and minimum (min) of these.
3. If max = 0 then the Color is black and Hue is zero.
4. If Red = max, then Hue = 60 * ((Green – Blue) Mod 6) / (max – min))

What is the difference between value and saturation?
