Abstract in Multiple Colors

This painting began with several random strokes on the canvas, each in a different color.  From there I began applying dots and dashes, which radiated in various directions from the original brush strokes.  The radiating patterns interacted with each other, creating an energetic flow.  In stage 3, I applied very thin glazes of strokes of lower value (dark gray purple) in vertical lines and arcs.  The effect gave an architectural feel to the abstract image below, so I added horizontal lines, vaguely like stairs.  Perhaps this is an homage to Piranesi's engravings of imaginary architectural settings.
