first thing i would probably do when trying to figure out the color of a panel would be to look at the panel. ;)

in all seriousness though, the only time i can see this being an issue is if two panel options are available for a single module and it only has one entry in the database. most of the modules with multiple panel options already have separate entries already though.

when you enter a module in, if there was a field where you can select [black][silver][other], and then make this an option when filtering results of a search... im not really seeing what the issue would be from an implementation perspective?
