What color is Sherwin Williams Proper Gray?
Sherwin Williams Proper Gray SW 6003 is a light-to-medium gray with a muted, subtly warm cast that keeps it from reading icy or stark. Its low saturation gives walls a soft, grounded look, while the slight beige-brown influence becomes more noticeable beside crisp white trim. In bright natural light, Proper Gray can appear clean and gently pale; under cooler north-facing light, it may lean more traditionally gray. It suits living rooms, bedrooms, hallways, and painted cabinetry where a quiet neutral is needed without the heaviness of a darker charcoal. Pair it with warm white, natural oak, aged brass, linen upholstery, or deeper mushroom and charcoal accents.

LRV of Proper Gray
Proper Gray has an LRV of 39.44% 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 39.44%, 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.
