Lets you independently control ore colors ingame and in the minimap, including making them invisible!
Small changes concerning balance, gameplay, or graphics.
Why are you need to change the colors in this way?
As on mixed ore everywhere maps the colours are too bright and not good on stream/YouTube.
Immersion, duh! Do you think ores in real life are colorful. They are just ROCKS! (Well, they sometimes are bright and colorful, BUT USUALLY NOT!)
