Changing Faction Colors

[QuestionMark]

I'm trying to change the colors of factions on the campaign map by using the descr_sm_factions file. I'm trying to make Armenia use a gold color for the main color, and black for the secondary. Everytime I change the RGB values, the game won't run. The screen just minimizes after I open it. It works fine if I just switch faction colors around, though. It will not work if I switch primary or first color. Is there some trick to use with the RGB values, or can you only use the color arrangements given already?

Not sure but I thought you could use any colour....

You sure you got the format right? as in the gaps between the numbers...

I'm sure about the format.
