What color is Valspar UK September Sea?

Valspar UK September Sea X136R267B is a muted blue-green with a noticeable grey cast, giving it a grounded, mid-depth appearance. Its cool teal direction is softened rather than bright, so it can bring color to a room without dominating the scheme. On broad walls, September Sea suits bathrooms, bedrooms, and studies, particularly alongside warm white trim or pale stone flooring. Pair it with oak, aged brass, linen, and soft clay-toned accessories to offset its cooler undertones. It also has enough depth for kitchen cabinetry or a painted interior door where a quiet alternative to standard grey is wanted.
