I think the old bias against green went out with the introduction of corporate sponsorships. Force does OK with Castrol green (paint and $$$). Yellow is hard to make look good with another color. Almost every combination is horrible. I swear a lot of guys are color blind. If I was going to pick a yellow, I'd use a yellow candy over white pearl with very small accents in cyan and magenta (these are 120 degrees off of yellow on the color wheel). The emphasis is on small amounts. Equal amounts look terrible.
