Today I just picked up a pair of used sram omnium cranks on craigslist and it came with neither chainring or GXP bottom bracket; hey I can't blame the seller because you can't beat the price I got them for.
Anyways, from some research online I found there's actually different model GXP BB's for road and mountain; and then the different sram groups.
Anyways from what I remembered when I viewed my complete 1st set in my LBS right before they installed them for me; the BB appeared transparent. Just like this one:
