#666a6d - Midnight Grey color

This cool, muted slate-gray carries a soft blue-green undertone and reads as a subdued, pewter-like neutral. It’s mid-dark in value, neither stark nor heavy, offering a calm, modern presence with subtle metallic depth. Ideal for minimalist interiors, industrial accents, or fashion basics, it pairs beautifully with warm woods, soft creams, mustard accents, or blush pinks. The color evokes overcast skies and wet pavement—understated, sophisticated, and quietly atmospheric without feeling cold or austere.
