Changing interface font and color

How do you do it? I dont have a clue about it so I would appreciate your help.

The WE Interface? Or the interface in-game?

WE's simple, it's File>Preferences.

I don't know about in-game.

I need in-game

I *THINK* to change font ingame you import the font you want, and rename it to the font that's in the War3.mpq (FizQuatd or something) and then change the path so that it matches the original. As for Color, I have no idea
