I painted a similar background on two new abstract paintings, but then went in different directions. In this one I used a thin black acrylic paint and a 1/2" brush to paint loose line-like marks. Then I drew lines in parchment and bright aqua green to brighten the overall image.
It feels very different from the first painting I finished.
