Cornforth White is a light grey that leans neither warm nor cool. Between Ammonite and Purbeck Stone, it forms the mid tone in the Farrow & Ball Easy Neutrals group. Try it as a wall colour with the lighter Ammonite on the ceiling and trim for a put-together all-grey look.Estate Emulsion is Farrow & Ball\'s signature finish for interior walls and ceilings. Its distinctive chalky matt finish minimises imperfections, and scatters light to fully express the depth of their colours. The flat, velvety effect it creates even brings added richness to darker colours.
