Any truth to the practice of BLACK painted parts dissipating heat better?

I can debunk this myth with 2 flavors.... Chocolate ice cream melts faster than vanilla.

Not only that, but this......Helped Josh with a 5th grade science fair project 3 years ago. The theme was do light or dark colors get hotter. We painted 4 aluminum panels. White, yellow, green and black. The black one was always warmer in all settings. In the sun, in the shade, under a halogen flood light and even just lying on the garage floor.

Also, sitting in the sun, my buddy's dark blue Ram was always hotter inside than my white Ram.
