What Color Is Dark Harbour, Really?
Dark Harbour reads as a cool blue-green tone — very dark — reads black in most rooms. The notes below cover how Benjamin Moore CSP-720 behaves in different light and the closest matches at competing US brands.
Best Rooms and Uses for Dark Harbour
Dark Harbour 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.
How Lighting Changes Dark Harbour
At LRV 8, Dark Harbour 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.
Most complaints about Dark Harbour 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.
Need It From Another Brand?
