I actually think the orange looks surprisingly decent and thought about it for mine. I hate brass and have pulled it from some of my games. Only one I've left it on for now is ToTAN, but even thinking about black there too.
For IJ, I had thought brass because everyone does it, but I ended up doing a "leather hat" brown that is pretty cool. Much more subtle. In darker lighting it isn't far from black, but in better lighting it basically matches Indy's hat / whip. Got it done by Matt at Back Alley. Not for everyone, but a nice option for the non-brass folks.
