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.Exterior Eggshell brings long-lasting colour to outdoor spaces with a finish that remains flexible once dry, protecting wood and metal surfaces through changing weather. Added preservatives help to prevent the growth of algae and fungi, and the resin-rich formula resists flaking, peeling, and fading for up to six years. Providing it has been applied in accordance with Farrow & Ball Product Advice Sheets. Not suitable for use on exterior plastic surfaces or decking.
