What color is Behr Forbidden Red?
Behr Forbidden Red PPU1-10 is a muted, medium-dark red with an earthy, softened cast rather than a bright, clear crimson look. Its balanced red-brown character gives it visual weight, making it especially effective on a dining room wall, a library, or a front door. In strong daylight, the red reads more clearly, while evening light can make this shade appear deeper and more grounded. Pair Forbidden Red with warm white trim, charcoal, blackened bronze, or natural walnut for contrast that does not compete with its depth. It can also bring definition to cabinetry or an accent wall when the surrounding palette is kept light and restrained.

LRV of Forbidden Red
Forbidden Red has an LRV of 10.5% 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 10.5%, 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.
