Do black roofs make houses and attics hotter than light colored roofs?

Not enough to worry about if you are considering a black roof for cosmetic reasons. Once the asphalt base is heated, that is what is transfering the heat. Asphalt heats up and holds it. A lighter color is going to reflect some, but a miniscule amount. For a cooler attic, there are materials such as radiant barrier along with proper venting that contribute to a cooler attic.

In field tests of different roofing materials and attic venting it was found that the only factor that made a significant difference in the temperature of the shingles was the color. The lighter color the cooler the shingles so it's hard to say how effective grey would be.

A radiant barrier will reduce the heat transfer to the attic floor and so will insulation.

I was looking at Timberline Cool Color Shingles. I haven't seen them in real life yet. Anyone with opinions? Are they a gimmick?
Not sure I want to sacrifice appearance for energy savings. . .
