About Poseidon
Poseidon (664) is a deep, medium-strength green from Benjamin Moore that leans blue. With an LRV of 30, Poseidon absorbs more light than it reflects, so it works best in rooms with good natural light or where you want a cozier feel.
North-facing light makes Poseidon read cooler and slightly darker, while warm south-facing light softens it. It's a good fit for bedrooms, offices, kitchen islands and cabinets and accent walls. Next to Palm Coast Teal (733), it's darker and more colorful.
