What color is Valspar UK Poseidon's Castle?

Valspar UK Poseidon's Castle X95R179B is a mid-depth blue-green with a restrained grey cast that keeps it from looking overly bright. Its cool teal character is clear in daylight, while lower or warmer lighting can bring out its softened, smoky side. Use it on a study, bathroom, or dining-room wall where a more grounded colour can give definition without making the room feel heavy. Poseidon's Castle also suits painted cabinetry or a single architectural feature, paired with warm white trim, pale oak, aged brass, and natural linen. For contrast, add clay-toned accessories or muted terracotta, which brings warmth against this color’s blue-green base.
