1% Brightness :
10% Brightness :
>30% Brightness

Suggestion for
@Anders_ASUS @LP_ASUS @CH_ASUS you could see that greens and blue are always higher than reds. Keeping these sliders fixed (though I've changed) there is an inverse relation between "brightness" and "filter strength" .
Brightness ∝ (1/ filter strength)
May be you could use these knowledge to find a solution.
