Dulux Mountain Air 21GY 88/066

Dulux Mountain Air 21GY 88/066 is a very pale, softly muted green with a noticeable yellow cast that keeps it from reading icy or blue. Its high lightness gives walls an airy, lightly washed appearance, while the modest green saturation remains visible rather than fading into plain off-white. In daylight, Mountain Air can look fresh and botanical; under warmer artificial light, its yellow-green undertone is likely to come forward more clearly. It suits kitchens, garden-facing rooms, and bedrooms where a gentle color is wanted without using a neutral beige. Pair it with chalky white trim, light oak, woven natural fibres, or muted clay and olive accents for a grounded palette.
