[Xiaomi Redmi Note 7 ROMs, Kernels, Recoveries, & O] XeoNoX:
I must admit the default of most of these non official roms hurt my eyes, you can however change the screen colors to your personal liking also note that these settings will also effect the "BRIGHTNESS" of the screen for those that have slight brightness issues:

Note: If you have previously changed your RGB/Color/Display settings in your rom i would recommend you put them back to default vaules within the stock ROM settings:

<SETTINGS><DISPLAY> COLOR SETTINGS>

<SETTINGS><DISPLAY> NIGHT LIGHT>

Put the above back to the stock rom settings PRIOR to proceeding below.

For those that wish to change the Color Profiles on their rom to have a better viewing experience:

Allows changing of RGB ( Red Green Blue ) , Saturation Intensity , Gray Scale , Hue , Screen Value , Screen Contrast
