What colour?

As you can see, Surfer boy undercoated the outside of the van on the weekend which brings me to colours!  We're trying to decide what colours to paint the exterior.  I have a general idea but haven't quite decided. 

The roof and the stripe will probably be the same colour with a contrasting colour on the body.  It's a 1950's van so that also is a factor.

Wouldn't mind some suggestions - keep in mind the upholstery inside is a deep teal green.  What do you think?
