This discussion addressed the question request:
"Do you know how to change Just the Font Color, but without any conflicts?
For example, let’s say I have a Font mod Installed plus a Different HUD mod.
(both of which work great together)"

To change the color of the font like the question above, it depends on the mod itself.

You see, to change the font color you need to change it easily in the scheme file, like this file:

• clientscheme.res
  
• l4d360uischeme.res
  
• chatscheme.res

and there are other scheme files.
You can change some of the colors in the scheme file, but the problem is if you for example have other mods such as HUD we don't know the coding of the resource file for the color taking from the scheme or already colored directly to the UI element itself, in other words if it is colored directly to the UI element itself then even if you change it in the scheme file there will be no results.

So how to change the font color on a HUD mod you have, especially without conflict?
My suggestion is that you have to disassemble the mod itself and change a few lines of resource code,

Don't worry I gotchu, I've made a simple tutorial how to change font color, and hope this can help solve your problem:
