Haf 912 Custom Interior Paint Job?

Ok, here's the thing. I want to paint the interior of the Haf, because it being bare to me is just ugly. I know that I want fans to be blue led, so I need to figure out a color that will go well with it.

I'll be eventually either buying a side panel with a window or doing it myself, so the paint job is essential to me. The back of the case will be the same color as well.

So, what do you think? I was thing black at once, but that seems so plain. Also thought about yellow paint with gold metal flecks, but I would like other opinions as well.

Thanks!
