Farrow & Ball: Recipes For Decorating suggests a team of three shades: a pale colour for a fresh feel, a stronger one for a muted scheme, plus an accent colour that ties them all together and brings rooms to glorious life.
Look out for additions in your chosen accent shade to add to your home and, of course, channel Marie Kondo by only holding onto an item if it brings you joy.
