I've never been a huge Rothko fan [I could probably stand to slow down a bit when I go to museums and just sit in front of a painting for a minute or an hour,] but man, he really got experience design... and one could say the whole point of art for that matter:
The people who weep before my pictures are having the same religious experience I had when painting them. And if you say you are moved only by their color relationships then you miss the point.
I’m not an abstractionist. I’m not interested in the relationship of color or form or anything else. I’m interested only in expressing basic human emotions: tragedy, ecstasy, doom, and so on.
