I mixed up individual pools of cobalt blue, aureolin and alizarin crimson, then using a large sea sponge soaked with water; I rolled it around on a dry sheet of paper.
I poured each of the three primary colours over the wet areas on the paper and rolled them around a little to let the colours mix together on their own.
Then I sprinkled some salt into the wet paint and set it aside to dry.
When I returned, I could see it things that looked a lot like coral and with the vertical column on the right side of the painting I think I will make this into the forecastle of an underwater wreck and add some reef fish to the painting to create more interest (see postings on 18 and 19 February 2010).
