Patrick Baty FRSA (born 1956) is a British historian of architectural paint and colour, who works as a consultant in the decoration of historic buildings.
He was educated at St Benedict's School, in London, and after a short period as a private soldier in the Parachute Regiment attended the Royal Military Academy Sandhurst being commissioned into the 9th/12th Royal Lancers in 1976. He resigned his commission in 1980 when his newly posted commanding officer opposed his secondment to the Sultan of Oman's Armed Forces. Reverting to the rank of Trooper he undertook Selection for the Artists Rifles leaving as a Captain some ten years later.
After a brief spell with the Anthony d'Offay gallery he joined his family paint business Papers and Paints. Having always had an interest in historic buildings he began a study of the methods and materials employed in their decoration. In 1993 he completed a part-time degree in the subject at the University of East London.
