It looked goldish to me but yes the nc is what im calling gold.
Left was silver on mine, middle was red, right was goldish uniforms?
There are 3 main colours that are used, TR is red, NC is blue, and VS is purple.
Suits always have a secondary colour, but those can be changed with skins to help you camouflage to the environment. The secondary colour on VS is almost always black, TR and NC have more grey/silver colour. I think the NC have some gold in them maybe.
I have vs on palos
The other 2 on gaudemala server
The reason red, blue, and purple are used is because that colour will always appear on your character. Also those are the colours used in game to identify which empire you belong too. The marker above someone's head will be red, blue, or purple. The map will be colour coded red, blue, or purple depending on which empire is in control of that section. Control points (the A,B,C markers) in facilities will show red, blue or purple depending on who's currently in control of that point. The shields on heavies and on engineer's turrets will be red, blue or purple, etc, etc...
