How you can examine that body of work and not come up with "minimalist," I don't know.
I also don't know why artists like Martin win critical acclaim, and artists who produce work like this don't:

OK, full disclosure, that was a blatant plug for my uncle. But this really goes to the heart of what art is. I don't see any value in minimalist abstraction. Looking at Agnes Martin's work, I'm just not left with any sort of feeling at all. She's got some nice color combinations, but so do interior decorators and web designers.
Despite having written a novel about an artist, I have barely begun to study the topic. But one thing I am sure of. Art is not only the skillful execution of the steps necessary to produce a product: that's craft. Art evokes an emotional response. Not just "that's an interesting arrangement of _____" (words, sounds, colors). But "Wow, that really makes me feel _____" (peaceful, sad, joyous).
If art were just the pleasant arrangement of colors, then a lot more people would deserve the kind of recognition Martin got.
