About Blue Grotto
Blue Grotto (CC-964) is a very dark, medium-strength purple from Benjamin Moore that leans blue. With an LRV of 5, Blue Grotto absorbs most light. It creates a dramatic, enveloping look and suits accent walls, cabinetry and well-lit rooms.
North-facing light makes Blue Grotto 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. Next to Admiral Blue (2065-10), it's warmer.
How Blue Grotto changes with the light
Blue Grotto 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
Blue Grotto will read even deeper in north light: great for a cozy, enveloping room, less so if you want it bright.
East-facing rooms
Blue Grotto 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 Blue Grotto from feeling heavy, so deep colors work well here.
West-facing rooms
Blue Grotto looks cool in the morning and warms up in the golden late-afternoon light.
