About Dark Harbor
Dark Harbor (CSP-720) is a very dark, muted blue from Benjamin Moore that leans green. With an LRV of 5, Dark Harbor absorbs most light. It creates a dramatic, enveloping look and suits accent walls, cabinetry and well-lit rooms.
North-facing light makes Dark Harbor read cooler and slightly darker, while warm south-facing light softens it. It's a good fit for accent walls, front doors, cabinetry and powder rooms. It's very close to River Blue (2057-10); you'd mostly see the difference side by side.
How Dark Harbor changes with the light
Dark Harbor is a deep color. In north-facing or dim rooms it reads darker and cozier; in south-facing rooms it shows more of its color. Either can work, depending on the mood you want.
North-facing rooms
Dark Harbor will read even deeper in north light: great for a cozy, enveloping room, less so if you want it bright.
East-facing rooms
Dark Harbor will look warmer and brighter in the morning and cooler and grayer by afternoon; check a sample at both times.
South-facing rooms
South light keeps Dark Harbor from feeling heavy, so deep colors work well here.
West-facing rooms
Dark Harbor looks cool in the morning and warms up in the golden late-afternoon light.
