About Sherwin-Williams Mild Blue
At LRV 65, Mild Blue is a light color that bounces daylight around a room without tipping into stark white. Its blue undertone is the part to watch: it gets picked up by whatever sits next to it, so test it against your trim, floor and the room's main light before committing. It holds its undertone in most exposures, which is what makes light shades like this so forgiving room to room.
Mild Blue is an easy whole-room color for living spaces and bedrooms, and light enough to carry onto trim or a ceiling if you want a soft, seamless look. Grays like this read as a modern neutral and sit comfortably alongside both warm woods and cool metals.
