What color is Valspar UK Shale Blue?
Valspar UK Shale Blue X101R197A is a deep, muted blue-grey with a noticeably cool cast and low-key, smoky character. Its #485560 value gives it enough depth to read as a strong wall color, especially in studies, dining rooms, or bedrooms with good natural light. In brighter conditions, the blue-grey quality is clearer; under warm evening lighting, it can appear softer and more charcoal-leaning. Pair Shale Blue with off-white trim, pale oak, brushed nickel, or slate-toned stone to keep the scheme grounded. It also suits kitchen cabinetry or a painted interior door where a dark neutral is wanted without using black.
