I see alot of posts from the design perspective but what is your brand trying to convey? Who are your customers? The sure fire way is to generate lets say 20 schemes, get friends, family, and biz partners to vote on their top 5. Get a collection of top 3-10 color schemes and show them to possible customers. Take their input and there you have a color scheme that has a high likelyhood of working for your target market. Attractiveness does not equal branding good, ex this famous brand: http://www.arrogantbastard.com/
As you see the color schemes are only there to accentuate the brand. Do customers buy teslas in order to be green or because their a luxury sports car? Their color scheme is chosen on the basis of their brand and who their customers are.
The colors you choose shouldn't matter on what others choose. The colors you choose should convey your brand. Doing something different with your color scheme may even be a benefit in regards to being the purple cow.
