What color is Benjamin Moore Rocky Mountain Sky?
Benjamin Moore Rocky Mountain Sky 2066-40 is a clear, high-energy blue with a noticeable cyan cast, sitting between bright sky blue and saturated aqua. Its crisp, cool character makes it especially effective in sunlit bathrooms, laundry rooms, and children’s spaces where a clean shot of color is welcome. On a feature wall or painted cabinet, Rocky Mountain Sky brings stronger definition than a pale blue without reading as navy or teal. Pair it with clean white trim, pale ash wood, soft gray, or sandy beige to give the blue room to stand out. In lower light, this shade will appear deeper and more blue-forward, while bright daylight draws out its vivid turquoise-blue edge.

LRV of Rocky Mountain Sky
Rocky Mountain Sky has an LRV of 31.02% and refers to Medium colors that reflect a lot of 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 31.02%, 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.
