There's a fabric treatment called "coldblack."

We were tandeming (144 team age) up a long hot event climb when we caught(!) a slim, fit-looking rider completely covered in black. He wasn't doing well and was sagged off the course. We guessed he was a victim of this hype.
I prefer skin-tight light colored technical fabrics for riding in the heat.
