About Rust-Oleum Blue Harbor
Blue Harbor sits in the mid-range at LRV 36, so it shifts visibly through the day — lighter and more open in morning light, deeper and moodier after dark. 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. South-facing rooms will pull it lighter and warmer, while north light cools it down.
Blue Harbor is versatile enough for full rooms but has enough depth to anchor a space, so it suits living rooms, bedrooms and cabinetry alike. Teals add character without shouting — good for a vanity, an island or a feature wall.
