I know this is a hard, but when I was a kid I had a book about a town that asked some Easter Bunnies to paint the town for Easter or the Easter Bunnies just painted the town or one Easter Bunny painted a bridge or there was one Bunny that painted the town. There were painting and bunnies and the whole town ended up being painted!
To help the painted buildings and things looked almost exactly like how this car came out, same colours and everything.
