Benjamin Moore

Sea Star

2123-30

Sea Star blends green, blue, and gray into a mid-tone with an LRV of 32.99, placing it in a lower-reflectance range that reads as a definite color statement on walls. The teal-gray lean gives it a cooled-down quality, and it can shift slightly more green or more blue depending on surrounding materials and light temperature. Chantilly Lace and White Dove work as high-contrast trim pairings, while Quiet Moments and Silver Mist offer analogous support.

Hale Navy or Kendall Charcoal provide substantial depth when used as accents.

Sea Star in Different Light

Light temperature is measured in Kelvin: a warm 2700K bulb pulls colors toward yellow, while 5000K daylight reads cooler and truer. Check the color at the time of day you actually use the room.

LRV measures how much light a color reflects, from 0 (black) to 100 (pure white). Below about 50 a color needs good lighting to avoid going flat, 60 and up helps brighten a room, and most whites sit above 80.
