I'd be very careful or you'll turn it into a rice mobile. Painting the hood, trunk and bottom of the doors will make it pure rice. Definately do not do that!
I'd say it's of questionability whether all those parts look alright together or not. In a way they do but in another they don't. I'd say paint the whole car a similar blue or leave it as is. Just be careful, I haven't seen too many two-tone cars that actually look that good. The two that are on here that are silver and black or whatever the other color is are actually very nice looking jobs.
