I think the manufacturers are slowly introducing Neon colours on bikes. Kinda gaudy for some but I like it personally.
If you're sick of the boring colours then Trek *ahem* Neil Pryde has a customized option.
PS
I'm an owner of a Blk/Red/White and a Naked Carbon finish bike. I'm thinking of getting the B/R/W repainted to some Neon colour matched with Grey but that's also the wife's bike soooo that'd be up to her.
