What color is Benjamin Moore Summer's Day?

Benjamin Moore Summer's Day CSP-780 is a muted mid-tone green with a gentle gray cast and a subtle sage character. Its low-saturation finish keeps the color grounded rather than leafy or bright, making it especially useful for full-room walls in bedrooms, studies, or quiet living areas. In clear daylight, the green reads more distinctly, while lower or warmer light can pull out its softened gray side. Pair Summer's Day with creamy off-whites, weathered oak, natural linen, and charcoal accents for contrast. It also has enough depth for painted cabinetry or a front door where a restrained green is wanted.

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 32.32%, 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.
