Just do a google image search for skoolie or guatamala chicken bus. If I had the $, I'd go with oyster shell white that was popular on cadillac and infinity a few years back. With a soft blue and green accent, scallop paint job style. To each their own.
Given that no two computer displays are alike...you can still get close by just Googling "Automotive Paint Charts". Tons, make that tens of thousands of colors available to get you in the ball park. Or go to any auto paint supply company to see the charts in person for more accuracy.
The color I am lusting after is from a 1939 Cadillac.
