Days after the Calais Jungle was cleared in October 2016, workers from refugee charity Migrate Art returned to find ghostly reminders of the day-to-day lives of its inhabitants strewn across the earth. Perhaps most poignantly, on the site of the school, were scattered coloured pencils and crayons. The team gathered these art materials and set up Multicolour, a project that sends them to leading artists – including Anish Kapoor, Rachel Whiteread and Edmund de Waal – to create works. The pieces will be auctioned at Phillips’ 20th Century & Contemporary sale in London in early April in aid of four migration charities – RefuAid, The Lotus Flower, Refugee Community Kitchen and The Worldwide Tribe – with 90 per cent of profits being divided equally between them. Bids can also be cast online at Artsy.net and Phillips.com.
