What color is Little Greene Ultra Blue?
Little Greene Ultra Blue 264 is a deep, high-saturation blue with a clear violet edge, based on its intense #211ACA color value. It reads cool and energetic rather than muted, bringing strong definition to a room without slipping into navy. On a full wall, Ultra Blue can create a dramatic backdrop for pale woods, crisp white trim, and brushed metal details. It is especially effective on cabinetry, a bookcase, or a painted door where its concentrated color can become a deliberate focal point. In lower light, the shade will appear darker and more inky, while brighter daylight reveals its electric blue-violet character.
