OP, if (big IF) the color does not go through the entire top layer, you might be able to have the color ground off, and then repainted. We recently had this done on our lanai. Driveways by Jay through Hometown Services did the project. He also applied twice the normal amount of shark grip so we have a nice non slip surface, about 400 square feet was around $1400. As mentioned above, it might be cost effective to just get a new driveway. Good luck with your project.
