If you want to make the colors look less saturated and more similar to the original Gothic then try this reshade-preset that I made:

For the best results disable Post Processing in the game menu.
You can also use these console commands:
- FOV 90
- r.bloomquality 0

Download reshade here: https://reshade.me/

When installing reshade, make sure that you use the GothicRemake.exe in THQBCNP1\GothicRemake\Binaries\Win64.
Not the one in the THQBCNP1 folder.
