Harbor Side Blue

740

Harbor Side Blue is a deep aqua with balanced blue and green components and moderate saturation. At an LRV of 40.31, this mid-tone shade provides noticeable color presence without making spaces feel dark. The undertones lean slightly toward green, distinguishing it from pure teals.

This color works in living rooms or bedrooms where a pronounced cool tone is desired without overwhelming the space. Benjamin Moore White Dove and Simply White brighten the palette, while Kendall Charcoal and Hale Navy add depth. Guilford Green and Wythe Blue serve as related cool-toned companions.
