"There is no such thing as good painting about nothing." That's a quote from the artist himself. Says something, doesn't it? Hang one and you're instantly aware: Rothko was finding something. Don't see it as abstract. Beauty is as concrete as anything.
We've read that Mark Rothko considered his paintings to be his children. And you know (possibly first hand) how scary it can be to imagine your children carrying on without you. Hang one of these in your home and revisit it, because these specific children are pretty wise, and what they say might just make you think.
