Avenue Blue™: a deep, ink-rich interior emulsion the colour of a city avenue just after the streetlights come on.

A saturated gemstone blue with the depth of wet ink and a faint green undertow that rescues it from corporate navy, Avenue Blue™ is Knuckles' most assured deep-blue interior emulsion paint. An ultramarine-leaning blue, it reads like the inside of a fountain pen, like indigo selvedge denim soaked dark, like the moment a winter sky tips from blue to black.

In bright daylight Avenue Blue holds its line: a clean, confident French navy that looks tailored against white woodwork and pulls the eye through a room. As the light softens it deepens to a near-velvet midnight, the kind of blue that swallows lamp glow and gives it back warmer.

A shade made for rooms that want to feel anchored. Studies and home offices. Hallways and panelled libraries. Dining rooms that double as bars. Bedrooms that prefer cocoon to conservatory. Paired with chalky white, soft warm grey, unlacquered brass and natural oak, or against Knuckles shades like Haberdashery and Rain Coat, Avenue Blue does the heavy lifting that good navy has always done.

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. Avenue Blue is a shade that earns its keep after sundown.
