I started with the brushes and was working purple on white. It was an interesting start, but it wasn’t quite what I was after. Then I put the spirals in place and applied one of the blending options (I forget which) and this amazing thing happened. I’m pretty sure it’s channelling E4, although entirely unintentional.
