What color is Behr Beta Fish?
Behr Beta Fish M450-7 is a deep blue-green with a muted, smoky cast that keeps it from reading overly bright or tropical. Its medium-dark value gives walls noticeable presence, while the softened saturation makes it especially effective in studies, dining rooms, or powder rooms. In bright daylight, Beta Fish can show more of its cool teal character; under warmer lamps, it tends to look greener and more subdued. Pair it with warm white trim, natural oak, aged brass, or terracotta accents to bring out its grounded side. It also makes a strong choice for painted cabinetry or a front door against pale stone or creamy siding.

LRV of Beta Fish
Beta Fish has an LRV of 10.84% and refers to Medium Dark which means that this color reflects very little light. Why LRV is important?
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 10.84%, 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.
