oh and a few more famous brands to back my argument for colors focus on your brand (story)... http://www.google.com http://www.purwater.com/#/healthy%20water,%20healthy%20you http://www.toyota.com/prius-hybrid/ http://www.teslamotors.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.
