About PPG / Glidden Sea Glass
At LRV 9, Sea Glass is about as dark as paint gets — it reads near-black on a wall and reveals its character only in direct daylight or under warm bulbs. 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 rooms with little natural light it can feel heavy, so reserve it for spaces you want to feel enveloping.
Sea Glass earns its keep as a statement: accent walls, a front door, cabinetry, a moody powder room, or exterior trim where you want sharp contrast. Teals add character without shouting — good for a vanity, an island or a feature wall.
