This photograph shows a painted wall in the back parlour on the ground floor of John Wesley's House. The small door which can just be made out in the wall is a recessed (or secret) wall door.
The wall colour, a shiny green-grey oil colour, also once known as 'French grey' or possibly 'pearl', came to light during refurbishment works in 1994-5. It was found in most rooms of the house and, likely, it is the original colour. This would have been used throughout the house, probably excepting the main parlour, as it was cost saving. In the 1700s using the same colour for most of the house was the standard way of painting interiors, except in well-to-do households and mansions.
