Rain Coat™: a bright buttercup-yellow interior emulsion named for the mac that rescues a grey day.

A sunny yellow with a whisper of green and a honeyed core, Rain Coat™ is Knuckles' most cheerful yellow interior emulsion paint. The colour of a buttercup held under the chin and the underside of a waxed lemon, it's engineered to light up the dullest corner of a British winter.

In bright daylight Rain Coat sings, genuinely: a proper clean yellow that lifts hallways and glazed-out rooms. In softer light it deepens to a honeyed mustard that reads warmer and more grown-up.

A colour made for rooms that need rescuing from grey days. Hallways. Kitchens. Children's rooms. Garden rooms and sun rooms. Paired with soft grey, chalky white, navy trim and natural wood, Rain Coat gives a room the easy lift of putting on a good coat and going out in the weather anyway.

Crafted the Knuckles way: a high-pigment, ultra-durable interior emulsion with Class 1 wet scrub resistance, an ultra-low VOC formula (<1g/l) and a chalky flat matt finish that feels like fresh plaster. Every tin is mixed to order in Great Britain, vegan-friendly and eco-conscious by design.

One litre covers approximately 14m². Touch dry in 2 hours, recoat after 4. Two coats recommended for the full depth of colour. Order a hand-painted sample first. Rain Coat is a shade that deserves to be met in your own light.
