Neatly filed away in the Charlotte Perriand archives in Paris, six unpublished colour studies for a series of woven panneaux ouvrants or ‘opening panels’ dated 1972 for the Pierre Blanche building at Les Arcs 1600 ski station have laid untouched for half a century. Today they are brought to life for the first time as a collection of hand-knotted rugs by CC-Tapis, presented on the occasion of Paris Design Week 2023 in an exhibition celebrating Perriand’s unpublished archives and her mastery of colour.
