Charles Roberson was one of London’s leading colour-makers in the 19th century. Setting up in 1810, he sold his own preparations of colour from premises in Covent Garden, to a distinguished clientele that included Turner, Sargent and Whistler, as well as William Morris, Queen Victoria and later Winston Churchill. Over its 200 years, the company has branched out to make a wide variety of artists’ materials, from colours and mediums (many of them to the same formulations as Charles’s own) to pens, paper and craft kits.
