New look for iron, copper and uranium ores. Now, they have colors of real ores, not refined metals.
Also, uranium ore glow is decreased to 70%.

Mod category: Tweaks
Small changes concerning balance, gameplay, or graphics.
I have no idea if this would be the right choice but you can use map colors:
iron = {r=157, g=82, b=63}
copper = {r=91, g=155, b=135}
uranium = {r=183, g=194, b=51}
