Sap Green is from the Colour by Nature palette, created in collaboration between Farrow & Ball and the Natural History Museum. It\'s a true olive green, much earthier and warmer in tone than the other greens in the Colour by Nature palette. It makes a great starting point for a Mid-Century Modern colour scheme, and looks particularly rich in smaller spaces.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.
