What color is Behr Iron Mountain?
Behr Iron Mountain N520-5 is a medium-depth gray with an almost neutral cast and a faint softened warmth rather than a sharp blue edge. Its muted, low-saturation appearance gives walls a grounded look without reading as heavy charcoal. In bright daylight, this shade can appear cleaner and slightly lighter, while lower or warmer lighting brings out its softer gray-beige side. Use it in a living room, office, or bedroom where you want definition without a dramatic dark finish. Iron Mountain pairs well with crisp white trim, pale oak, black metal fixtures, and natural linen or stone textures.

What are Behr Iron Mountain undertones?
Iron Mountain is a midtone, near-neutral charcoal gray. Its chroma is so low that assigning a specific hue-based undertone would be misleading. Because it is close to neutral, nearby surfaces and the color of the light can noticeably change how warm or cool it appears.

LRV of Iron Mountain
Iron Mountain has an LRV of 17.91% 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 17.91%, 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.
