Thanks everyone. I have made a little test on a scrap piece of plastic (a lot larger than my 6mm model).
1. I drew thins lines of chocolate brown and green to give me an idea where the lines will be.
2. I mixed half of dark yellow with half of chocolate brown, remove most of the paint on a towel and then took a drybrush and push gently from one side of the chocolate brown line to the other.
3. Then, I mixed half of dark yellow with half of green, remove most of the paint on a towel and then took a drybrush and push gently from one side of the green line to the other.
4. Finally, with the same brush, I took a little bit of dark yellow paint, remove most on a towel and then gently push the brush over all the surface of the green and brown lines.
Here is what I have done with my technique. What do you think?
