What Color Is Gossamer Blue, Really?

Best Rooms and Uses for Gossamer Blue
Gossamer 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. Teals add character without shouting — good for a vanity, an island or a feature wall.
How Lighting Changes Gossamer Blue
At LRV 55, Gossamer Blue 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.
Most complaints about Gossamer Blue are a light mismatch. Upload a photo of your actual room and see it on your walls — then ask for the same wall in north light or evening lamps before you buy a single sample.
