About Sherwin-Williams Open Air
At LRV 70, Open Air is a light color that bounces daylight around a room without tipping into stark white. Its teal 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.
Open Air 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. Teals add character without shouting — good for a vanity, an island or a feature wall.
