Which color arcade buttons to go for?

[MaxOne]

So,

I'm getting closer and closer to just doing the arcade mod on my vci but i just wanted to ask what people thought about which colour buttons to go for?

I like the look of them all black but if sometime my mates use my vci and it'd be hard for them to remember which button was which?

Is that really an issue?

Only difficulty I could see with all black is that in a really dark environment, it may be difficult to see them. Personally I'd want something UV reactive, but that's just me. There have been a lot of different combo's of colors, and it's really a personal touch to your controller.
