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.Modern Eggshell is Farrow & Ball\'s toughest interior finish, adding colour and protection to wood, metal, and concrete surfaces. This ultra-durable eggshell is tough enough for floors, and it can also be used throughout the home on skirting, doors, kitchen cabinets, furniture, and radiators.
