What color is Sherwin Williams Mortar?

Sherwin Williams Mortar SW 9584 is a light, softened neutral with a pale greige cast and a gentle beige warmth. Its low saturation keeps it from reading strongly creamy, while the muted gray element gives the color a lightly weathered, plaster-like appearance. In bright natural light, Mortar can appear nearly off-white; in dimmer rooms, its warm gray-beige character becomes more noticeable. It is well suited to whole-room walls, especially in living areas, bedrooms, and hallways where a quiet background is needed. Pair it with warm white trim, oak or walnut wood, aged brass, natural linen, and deeper charcoal or earthy brown accents.

What are Sherwin Williams Mortar undertones?

Mortar is a light, very muted creamy off-white. 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 Mortar

Mortar has an LRV of 73.69% and refers to Off‑White colors that reflect a lot of 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 73.69%, 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.
