Irritated with myself that I missed the piece on PBS about Mark Rothko. I was reading a book by Mary Todd Beam, where she describes seeing an original Rothko in someone's home. I believe she said the room was dark except for a light on the painting. As she walked by she said "it looked like the painting was breathing". Rothko's later works have large blocks of color that almost seem to speak to each other. Color is so powerful. We here in Milwaukee are fortunate to have a Rothko at the Milwaukee Art Museum.
