For this image the colors in Monochrome #1 are reversed. Are these fuzzy black dots, or holes? They pop in and out like an optical illusion. The intent is not to create an optical illusion. Rather the intent is to explore the emotional response compared to the black on white version.
I do not mean an obvious emotion like you might experience with a painting or photograph of a child with a puppy. Rather something more like meditation. If you try to remove your expectations and quiet the inner narrative, what do you feel? Personally, what I find is not symmetric as might be expected with the mechanical color flip would suggest.
