Try sand blasting. You can get a wonderful surface and control exactly where
you want the surface to be matte by using electrical tape to mask off the
area you want to stay glossy. You still retain the color though it will be
muted slightly. I recommend experimenting on a less important piece until
you get the hang of it.
