The AUO B156HW01 V.4 and the AUO B156HW01 V.7 have extra color coverage, it covers 95% of the adobeRGB, and cover most of the sRGB too, which is good, but for general office usage, the colors could look over saturated and extra red or extra blue.
The best solution is to use a color calibartor, which costs around 100 USD for the cheap models.
The quick solution is to use the intel graphics color settings to reduce the overall saturation, reducing saturation of individual colors does not help, reducing saturation for red and/or blue alone ends up messing with the color balance.
From my testing, I found that reducing the overall saturation to -31 (from the default of ‘0’) helps allot, and the colors still look more saturated than on most cheap LCD panels.
