What color is Valspar UK Castled Rhine?

Valspar UK Castled Rhine W29c is a deep blue-green with a muted, slate-like cast that keeps it grounded rather than bright. Its dark value gives walls a close, enveloping look, especially in smaller rooms or spaces with limited daylight. In brighter light, the teal-blue character is more noticeable, while evening lighting can make it read as a near-charcoal navy. Use Castled Rhine on cabinetry, a dining room wall, or a front door with warm white trim, pale oak, aged brass, and soft grey stone. It also pairs well with dusty pink or clay accents for contrast that does not feel overly sharp.
