About Sherwin-Williams Blue Horizon
Blue Horizon is very light — LRV 77, close to white. It opens up small or dim rooms and keeps walls feeling airy. 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. In north light it can read slightly cooler; a warm white trim alongside keeps it from going clinical.
Blue Horizon shines on ceilings, trim and in small or low-light rooms where you need to stretch the light — and as a calm whole-home backdrop. Grays like this read as a modern neutral and sit comfortably alongside both warm woods and cool metals.
