On 4 November, Colossal highlighted James Payne’s Great Art Explained film about Henri Matisse’s The Red Studio. The painting dates to 1911; this is a new discussion, not a new artwork.

Return to a basic compositional question: what does colour do after we’ve chosen an attractive shade? It can connect scattered elements, alter depth and make a small outline hold its own against a large field. Testing that in a sketch is more interesting than labelling a palette bold.

Temporarily remove shadows and decorative details. Does the image still hold together? The exercise needn’t end in minimalism. Sometimes it simply reveals what was supporting everything while the details politely distracted us.
