I painted a free form design in liquid latex to begin this study. After it dried, I surrounded its perimeter with Permanent Green #1. In the inner border, I used a combination of ultramarine blue and lemon yellow. The paints were very watery and the dried latex acted as a dam. One can see heavier concentrations of color along the lines previously occupied by the latex resist.

I decided not to manipulate the white spaces that were revealed when I removed the latex. I plan to revisit this theme, thus the name Green Swirl #1.
