What color is Sherwin Williams Simple Stone?

Sherwin Williams Simple Stone SW 9521 is a muted, mid-tone gray-beige with an earthy cast that keeps it from reading cold or overly taupe. On walls, it has the quiet, weathered look of natural stone, especially beside oak, walnut, linen, and brushed brass. Daylight brings out its soft gray side, while warm lamps and evening sun reveal more of its beige warmth. It suits living rooms, bedrooms, entryways, and exterior siding where a grounded neutral is wanted without the starkness of pale gray. Pair Simple Stone with creamy off-whites, deep olive, charcoal, or blackened bronze for contrast.

What are Sherwin Williams Simple Stone undertones?

Simple Stone is a light, very muted sandy beige. The HEX sample has a subtle yellow-orange bias, but its low chroma turns that hue into a neutral-looking color rather than a clear yellow-orange. Warm bulbs can make it look creamier or more golden, while cool daylight may mute that warmth and pull it closer to beige or greige.

LRV of Simple Stone

Simple Stone has an LRV of 57.34% and refers to Light colors that reflect most of the incident light. Why LRV is important?

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 57.34%, 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.
