Gillian Ayres: A Life in Colour

A genuinely major show, not a regional footnote — 26 works tracing Ayres' explosive use of colour from her teenage paintings through to the monumental late-career canvases she's best known for. Free to walk into, which for a retrospective of this size is unusual.

It closes in early October, so this is one to catch rather than save for later — pay-what-you-can booking gets you priority entry if you'd rather not queue.
