Help me decide my new project car paint color

I am leaning towards one of the orange pearls that are 2 stage. The company is Urekem and is based in Mississippi within about a 1 hour drive for me. The rumor mills say some chemist from HOK started this company. They manufacture and will sell right at the factory location. I am going to give them a try since they are close and reasonable. My first purchase will be epoxy primer from them hopefully sometime next month.
Can't really decide also if I want the underside of the car the same color or just black.
