Hague Blue is a fantastically popular Farrow & Ball blue, a deep and inky favourite for walls, woodwork, and front doors alike. Try it as a darker accent to Borrowed Light, or all over for rooms that make a real statement.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.
