In UK my house had an area of concrete outside the back door, there was a canopy over but the sides were open. One summer's day I hosed it down and once it was dry I slapped on some terracotta coloured floor paint. No cats or dogs to think about there. It dried to a matt finish, not slippy, and looked a hundred times better than dirty concrete. Also easier to clean. I was quite pleased with it. I think it was sold there as garage floor paint, it wore very well.
Here my drive would be a much bigger area. I still think I could manage it myself using a long-handled roller. A dark green would make the drive visually less offensive. I don't know about heat reflection. I remember going to Sepang to watch the last F1 race held there, we were sitting under a covered stand but that evening I discovered I was sunburnt under the chin, reflection from the black racetrack.
