Imperial Purple is from the Colour by Nature palette, created in collaboration between Farrow & Ball and the Natural History Museum. It\'s a deep, intense indigo that appears almost blue in some lights. It has an undeniably luxurious feel that\'s apparent whether it\'s used all over, as a rich wall colour, or in smaller quantities, such as inside a cupboard or on a piece of furniture.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.
