From the artist:

‘Paradox’ was a design which evolved over time. Since 1986, I had been painting these round orb shapes and I was very interested in the way I could create light with color. This interest in light probably came from my fascination with psychedelia as well as studying the light work of Carravaggio, Vasarely and Agam (in particular) and has been a consistent theme in my work from the very beginning. This particular piece was a study with bright colors interrelated against cool colors. It was also a very balanced square design. I think that the way the cool colors in the background go from light to dark in the center gives the piece an interesting focal point and sense of balance. I have since done many different iterations of this design with these ideas in mind but none more effective than this.
