Farrow & Ball Multi Surface 2.5L Dead Flat Pitch Blue No.220 360 Sander Head Johnstone's Trade Professional Undercoat isPitch 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.
