Ash Grey is from the Colour by Nature palette, created in collaboration between Farrow & Ball and the Natural History Museum. It\'s a laid-back shade of grey with a definite green undertone. While relaxed enough to be used in all kinds of rooms, it\'s an intriguingly changeable shade, appearing more intensely green in bright natural daylight and more grey in darker areas.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.
