tbh color limits aren’t really an issue but something that would make sense like constant combat wear and what not. so stuff like suits, coats or anything that isn’t really handy to have in combat would be obnoxious
thinking more on the lines of cloaks, light armor to have decent protection but be able to move around in a ship without any fuss like regular cloths. while also being able to charge into battle, scavenger like armor stuff but more sea environment and coastal island focused and not being unnecessary too much
the player isn’t going to be thinking, wtf is he wearing a coat to battle because vanity exists and it’s a video game, no one really cares about how someone is dressed, and while other color nominations can work for a navy, the most common thought of is white and blue
