Color & Contrast

[rdt595]

Can someone tell me how I can use that screen color adjustment feature? I look at the manual and there's not even a section for it.
I guess I'm 95% satisfied with the display on my LG G4 because maybe on some shows I don't know any better.
But i'm currently on Netflix, rewatching various Star Trek series, and the blue of the blue uniforms and the red of the red uniforms is a little off. Trending toward green and maroon/purple respectively. Not overly annoying, but if I can make some minor adjustment to fix it I'd like to.
However, if the cure is worse than the disease, so to speak, I won't bother.

The screen color adjustment is very sensitive and takes a while to get it right. As far as left and right adjustments it needs to stay close to the center axis give or take 2-3mm. Top to bottom you should only need the top 1/4 of the screen. Here is a shot of my screen. Where I have the ring placed seems to be the best spot for me. If anyone thinks they have a better setting please post a screen shot.
