A lot of research goes into what’s best for which market. Different colors denote different tastes, outlooks and preferences. Unfortuantely, black is considered a bad-ass color associated with aggressiveness, dominance, soldiery, stealthiness, ninjas and the like. Champagne denotes civility, sophistication, artiness, elegance and what have you.
Guess which one is typically "American" to most market research departments? It’s all how we’re perceived. Despite my mention above about not judging the looks of something, I prefer the champagne look but I’m stuck with the black as well.
All the best,
