What color is Dulux Sea Urchin 2?

Dulux Sea Urchin 2 90GG 28/133 is a muted mid-tone blue-green with a noticeable grey cast, giving it a softened, mineral-like appearance. It sits on the cooler side without becoming icy, making it a grounded option for bathrooms, bedrooms, or a study with good natural light. In brighter daylight, Sea Urchin 2 shows more of its green-blue character, while lower light can make the greyed depth more apparent. Use it on full walls or painted cabinetry alongside chalky white, soft stone, pale oak, brushed nickel, and warm off-white textiles. For stronger contrast, pair this shade with deep charcoal or near-black details rather than bright, highly saturated accents.

LRV of Sea Urchin 2

Sea Urchin 2 has an LRV of 25.73% and refers to Medium colors that reflect a lot of light. Why LRV is important?

Light Reflectance Value scale illustration

Light Reflectance Value measures the amount of visible and usable light that reflects from a painted surface.
Simply put, the higher the LRV of a paint color, the brighter the room you will get.
The scale goes from 0% (absolute black, absorbing all light) to 100% (pure white, reflecting all light).

Act like a pro: When choosing paint with an LRV of 25.73%, pay attention to your bulbs' brightness. Light brightness is measured in lumens. The lower the paint's LRV, the higher lumen level you need. Every square foot of room needs at least 40 lumens. That means for a 200 ft² living room you'll need about 8000 lumens of light – e.g., eight 1000 lm bulbs.
