The Scottish Colourists were some of the most important and avant-garde artists working during the early 20th century. Their art was bold and vibrant and unlike anything that had been produced in Britain before. Sotheby’s upcoming sale ‘The Way of Colour: Pictures from the Harrison Collection’ (10 – 17 March) offers Fauvist inspired paintings by George Leslie Hunter, stunning still-lifes by Francis Campbell Boileau Cadell and Cezanne-like work by Samuel John Peploe.
