Paint is too personal, it depends what you like? If I were you I would start thinking of the theme of your machine.... do you want it to be pretty? do you want it to be tough? Do you want it to look like a GA chopper or a military style? Do you want it to be flashy or functional? There is so many variations to try to come up with one without seeing the finished machine IMO....
I guess looking around at the colors cars are coming out in these days and see if there is anything you like the look of?
There is nothing wrong with white, with colored areas of your choice in parts, or even wrap is good these days
What colors do you have in mund? What color is the other one in your pictures beside yours?
