A friend of mine asked me how to appreciate Modern Art. My humble response as an absolute amateur of art was:
1) Don’t try to come up with a explanation of the art work. Art, in particular Modern Art, is very subjective.
2) Open your mind and eyes to see if you like it visually or not. It could be the colors and/or the composition of the art work.
3) You don’t need to justify you like it or dislike it. You are entitled to have your own opinion and taste.
