Color Saturation Very High

Hi In Dudu 7 the color saturation is very high. To watch videos files I use CnX player which has saturation control and I can decrease it. But the system in general is oversaturated. Is there any ADB command that allows the saturation to be reduced?????
Could you implement sliders for saturation in the system configuration????
There is an application called Color Changer Lite and Pro version but they require root permissions.
Watching videos on YouTube is really impossible.

Yurii_Dubiaha Hello. Yes, from the beginning I found the colors very strong. I associate this with the fact that a 2000 x 1200 panel has a high pixel density and little black area without light, so the colors are much stronger than on a 1280x720 screen. But this must be compensated for from Android. The androis configuration does not have saturation control. It only has color profiles for people with dyschromatopsia. I attach a comparison of a video of a Lenny Krabitz recital where the yellow color is very strong and I adjust it with the color control of the Cnx player. But the same thing happens to me on YouTube and I can't adjust it. I also notice that some Android icons are very saturated.

JhonnyD But it is something impossible to know. I don't have another unit to compare. It just seems to me that most people like saturated colors. It seems to me that it is wrong mainly for a car unit where the image should not dazzle the driver. You probably won't notice it in that photo, but that bright yellow really dazzles.
My previous S160 unit this same video looks like the less saturated image without any type of color correction.

Yurii_Dubiaha Hi.The method to root published on the 4pda site Universal Root 7862-9863... is it compatible with Dudu 7????
I don't see the isec6318update file, which is part of the Dudu 7 firmware.

JhonnyD ok. Can it be done by obtaining the boot.img file from the dudu7 firmware????
Is there any guide to root dudu7????
