Offline processing: colour selection (I)

Each RGB channel has different sensitivity  the intensity perceived is in function of the projected Hue

Example: selection of n=3 colours

1) Select n equi-spaced Hue levels

Hue

2) Project the n Hue values with different Luminance values and interpolate their response curve.

3) Given the maximum and minimum levels of luminances that we want to perceive  the corresponding projecting luminances for every Hue can be chosed
