It\'s a deep, intense indigo that appears almost blue in some lights. It has an undeniably luxurious feel that\'s apparent whether it\'s used all over, as a rich wall colour, or in smaller quantities, such as inside a cupboard or on a piece of furniture.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.
