What color is Sherwin Williams Clean Slate?
Sherwin Williams Clean Slate SW 9621 is a very light, muted gray with a subtle cool cast and a faint green-gray undertone. Its high lightness keeps it airy on broad walls, while the low saturation prevents it from reading stark or icy. In daylight, Clean Slate can appear like a soft silvered gray; warmer artificial lighting may bring out a gentler, slightly warmer gray impression. It suits bathrooms, laundry rooms, and open living areas where a quiet neutral backdrop is wanted. Pair it with crisp white trim, pale oak, brushed nickel, charcoal accents, or muted blue-green textiles.

LRV of Clean Slate
Clean Slate has an LRV of 76.35% and refers to Off‑White 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 76.35%, 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.
