A collaboration between Petworth House and the Royal Academy, as part of the NT property’s year-long ‘celebration of colour’. This show features the work of eight current and recent RAs, namely Gillian Ayres, Frank Bowling, Sean Scully, Rebecca Salter, Tess Jaray, John Hoyland, Ian McKeever and Barbara Rae. There’s plenty more art on the walls of the country house, of course, from the likes of Turner and Reynolds.
