I originally put down the long yellow strokes.I worked with pastel colors at first: turquoise, light carmine red and cadmium yellow. I noticed a subtle spiral. I put in darker red drips, some Hooker green and darker blue-green splatters, adding a layer of complexity.

I used pen and ink to outline selected yellow shapes. To bring attention to the clockwise spiral organization, I added ink-lined fringes to each shape. I treated the blue blots in the same manner, to show a counter-clockwise spiral.
