What color is Valspar UK Sleepy Hamlet?

Valspar UK Sleepy Hamlet R237B is a muted mid-tone green with a noticeable yellow-olive cast, giving it an earthy rather than blue-leaning character. Its softened saturation keeps the color grounded on larger walls, where it can read as a calm leafy green in daylight and a deeper olive in lower or warmer light. It suits kitchens, utility rooms, studies, and garden-facing spaces particularly well. Pair Sleepy Hamlet with warm off-whites, natural oak, woven jute, and brushed brass for a layered, organic look. For more contrast, use deep charcoal details or dark brown wood rather than stark black.
