I found a mix that I would like to keep as reference. I have some extra Super Sculpey Firm polymer clay I bought from a guy who does effects in movies and also big sculptures for Club decorating. So I decided to do some experiments with acrylic paint.
Here can be seen more details about the amounts of polymer clay and acrylic paint color mix.
I liked the shade of colors, slightly earthy, i'm thinking to try these colors on some Hundertwasser inspired designs to see how it goes, I love this artist.
