Color Combo...What do you guys think?

Something crossed my so I'll throw it out. I have a 2000 Dodge Grand Caravan that is painted a color called "Deep Slate." It looks black most of the time, but when it's clean & the light hits it right you can see that it's really a very, very, very dark gray color. Would that work as a base or stripe color? Maybe if I had a gold metallic to the paint? Just kinda' thinking out loud here......
