Pitch Blue is a rich cobalt shade with a hefty dose of black pigment - hence the name. This gives it an indigo appearance that can seem almost purple in certain lights, and it really comes to life in south-facing rooms when teamed with the bright All White. For an altogether different, more restrained feel, try it in a darker room, or one mostly used in the evening.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.
