Calluna is a genus of plant that solely includes heather, whose dainty flowers inspired this delicate Farrow & Ball colour. It\'s a pale purple with a touch of black pigment, which makes for a soft and sophisticated shade that leans more towards lilac than pink.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.
