What color do I paint the dash?

Yessir. Its kinda matte in sheen. Not shiny not flat, but gives it the factory texture. Since i had done mine and sprayed over gray sandable primer, Id actually recommend priming, then shooting the part in flat black, and then spraying in light mist coats the textured black over that. This way you dont need as much to get the textured effect. When done it looks like the factory black.
