9. Adjust the blue white level (gain) on a minimal value
Note:
this minimal value is not necessary , provided that the 2 other colors are not influencing too much the color to be adjusted,
in fact the aim is to minimize the effect of the two other colors since there is a risk of reaching too soon the transition
(bright spots) due to the contribution of these two other colors signals.
