What color is Dulux Lost Lake?
Dulux Lost Lake 30BB 14/242 is a mid-depth blue with a muted, slightly greyed cast that keeps it from reading overly bright. Its blue tone feels cool and measured, showing clearer color in daylight while taking on a deeper, more subdued character in lower or warmer light. Use it on a study wall, bathroom cabinetry, or a dining-room accent where a grounded blue is wanted without the intensity of navy. Lost Lake pairs well with soft off-whites, pale grey, weathered oak, brushed nickel, and matte black details. On an exterior door or painted built-in, this shade gives a clean contrast against light masonry or warm white trim.
