How to prevent exaggerated LED color saturation in dark color tones.

[GorgiGR]

Hi there,

a rather common issue in DIY Ambient light systems (at least the ones I built and used) appears to be the fact that in dark scenes where the captured color hues are "dangerously close to black", the LEDs produce an unnaturally saturated light.
From a colorspace/mathematical perspective the colors are probably "correct" however the human eye, especially the cones that are responsible for color vision do not normally discern color that well in darkness, and in dark scenes this becomes painfully obvious. So I'd like to try out to fade out the saturation of darkes hues, like if I have an mean RGB value of (10,0,0) for an area, maybe instead drive the LEDs to show another color, equally bright but with less exaggerated red channel. Does this make any sense?
(Some people address this by using the backlight threshold feature, but for me it is not an option...)
So I was wondering if any of you has found a way to non-linearly reduce saturation in darker colors while keeping it almost untouched in mid and brighter tones. Is there a combination of e.g. gamma curves, temperature, RGB definition etc. that would do the trick?
