The warmest brown
London Clay is loaded with magenta pigment so is the warmest brown you could find, creating uncompromisingly glamorous rooms. If you are wary of such a strong colour on the walls of a living room, consider using it in a hall or transitional area where it will serve to make the rooms off it feel much lighter. London Clay is the perfect accent for both Elephant's Breath and London Stone. Dark Tones Undercoat.
