I think black might last longer in UV which isnt an issue below the car. If you wanted a material that last longer and looks better than coroplast buy alumalite. Alot of people make splitters and sometimes undertrays for their expensive sports cars out of that.
Otto is correct.

A reflective surface, such as shiny aluminum or a mirror for that matter is better at reflecting heat away from the coroplast.

White would be the next color of choice, even for keeping the sun's UV from degrading the material over time.

The worst color is black, which has the most absorption of visible light and/or UV.
