My painting instructor, while no particular fan of modern art, particularly dislikes Matisse's use of color, which he refers to as being "acid."
While I personally am inclined to like and enjoy all of the artists in this thread, I can't get over the feeling that they are almost more like fabric designers.
The Matisse paintings would make wonderful "tropical" Hawaiian type shirts (wouldn't surprise me if you can actually buy a Matisse shirt) while Kandinsky's stuff would look nice on a couch or drapes.
I think you're right. They do remind me of the cheap and gaudy upholstery fabrics one sees on poorly reconditioned antiques
