Roof paint for a car? (Repel heat / keep interior cooler)

I did some searching and didn't find much. I wanted to know what difference the particular color of a car makes. Obviously white is the best option for repelling heat, but my geo is a really light red color, and my curiosity was whether a particular color was better than any other (assuming the same...lightness?).

Also during my searching I found someone had brought up painting a car with white elastomeric roof coating as an idea to repel heat, and I wondered if anyone has heard of this.

I usually come up with the weird ideas.
