Modern Eggshell is Farrow & Ball’s toughest interior finish, adding colour and protection to wood, metal, and concrete surfaces. This ultra-durable eggshell is tough enough for floors, and it can also be used throughout the home on skirting, doors, kitchen cabinets, furniture, and radiators. A pale and traditional blue. This pale blue grey takes its name from the soft natural light that often pours through ceiling skylights. However, it is less reflective than Borrowed Light, reading as a definite cool blue when used in small spaces but becoming paler and greyer when used in larger areas.
