What color is Valspar UK Jellyfish Blue?

Valspar UK Jellyfish Blue R145B is a clear mid-tone blue with a cool, lightly softened appearance. Its balanced depth gives it enough presence for a full wall, while still feeling open in a bedroom, bathroom, or home office with good daylight. In bright natural light, Jellyfish Blue reads fresher and brighter; under warmer evening lamps, it takes on a slightly more muted blue character. Pair it with crisp white trim for contrast, or use pale greys, light oak, and brushed nickel to keep the scheme clean and understated. It also makes a practical choice for painted cabinetry or a single feature wall where a stronger blue is wanted without going overly dark.
