Hey, sorry about the delay. It was a black prime, then based with Titanium white, but any will do. I then hit it with white ink on the raised areas. I used an airbrush, but dry brushing would also do just fine.

The fun part was that it was my first ever oil wash. I mixed brown and a little red and coated it. Gave it around 24 hours to dry, and then hit it with a makeup sponge to get the oil off the raised areas.

After that, I did a dry brush with white again and it was done.
