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.Estate Eggshell is a washable, water based satin finish for interior wood and metal. Its soft low-shine finish brings an understated elegance to trim and furniture and is suitable for doors, kitchen cupboards, radiators, and other wood and metalwork throughout the home.
