Robin Greenwood considers "an important and relevant question to ask (time and again) about abstract art: what does distinguish it from design?" He continues: "Matisse's late work does contribute quite prominently, if not iconically, to a certain strand in the conjunction of modernism and abstraction which blurs the distinction between art and design, and more specifically between abstract painting and the decorative and applied arts… I’ve always considered Matisse’s greatest contribution to art not his colour, which is undoubtedly exceptional, but his inventive painterly architectures reasserting what [painting] does (what, in a way, it has always done), what it delivers, by the act of continual reinvention; finding yet more new ways to keep it alive – and of course, keep it keenly separate from design and the applied arts even when in the act of using elements of those very disciplines to elaborate and enrich the spatial structures of his painting."
