NES-inspired theme

I'm currently working on a multimedia station which will consist of a mini itx in the shell of an old NES running slackware. It'll be hooked up to my TV and stereo, and play my music, movies and of course feature a NES emulator.

As the music player I've chosen MOC since it really is perfect for the job.

I've made a skin to match the aesthetics of the NES, and would really appreciate some feedback and suggestions on how to improve it.

I also encountered a strange problem. The colours I've chosen to use are the NES colours, red, black, light grey and dark grey, but the only way I get the dark grey to work is if it's also bold. This is really annoying since the design I really wanted depended on usage of non-bold dark grey. If anyone knows how I can fix this I would really appreciate it.
