How do you change the color of Terrain types?

[unmerged(28727)]

The issue in question is for WATKABOI. That mod uses Grey for their mountains, I'm used to Grey being very extreme mountains like the Alps or the Caucasuses in games like HoI2 or Vicky, most of the Terrain in EU2 is actually supposed to be "hilly" not Mt. Everst type obviously.

The vanilla EU2 used brown which is what I prefer. How do I change the mountainous terrain type back to brown instead of grey?

Thanks!

Look into "Map" folder. There is a file "colorscale". There are defined colors. Play a bit with the RGB settings or replace the block defining mountain color with the vanilla values.
Sadly, I don't know what name of color the mountains have

I believe mountains are "dark orange".

Confirmed. Only problem is colors used for terrains are also used for countries on the political map. Check result of the change on both map modes.
