An abstract piece of art uses color, form, and line to extract feeling or expression from the artist. The form can be independent from visual worldly references. Departure from these references can be partial or complete, or even obsolete.
When viewing a piece, something about it might make you turn away immediately, maybe or zero in on a stroke, or have a general feeling of some kind wash over you…You could be disgusted or delighted or anywhere between or outside.
What makes you you and me me is what speaks to us and how, otherwise I think we are all pretty much the same.
