Scotch Blue is from the Colour by Nature palette, created in collaboration between Farrow & Ball and the Natural History Museum. It's the darkest blue in the Farrow & Ball palette and more intensely coloured than the blue-based black shade Railings, making for eye-catching woodwork or a deeply luxurious wall colour. Try it in Estate Emulsion for a particularly velvety feel.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.
