#00666d - Trouser Blue color

Deep marine teal with a cool, green-blue presence—rich and slightly muted. It reads as a sophisticated, shadowed turquoise that leans more toward teal than bright cyan, suggesting depth, calm, and understated elegance. The color evokes coastal lagoons, wet slate, and evergreen needles in low light. It pairs beautifully with warm creams, soft corals, brass accents, or pale greys, and works well in modern interiors, nautical themes, or branding that aims to feel steady, refined, and quietly confident.
