What color is Sherwin Williams Windy Blue?
Sherwin Williams Windy Blue SW 6240 is a light, muted blue with a noticeable gray cast that keeps it from reading overly sweet or bright. Its cool-leaning character suits bedrooms, bathrooms, and home offices where a clean, airy wall color is wanted without starkness. In bright daylight, Windy Blue can appear clearer and slightly more blue, while lower or warmer artificial light tends to bring forward its soft gray side. Pair it with crisp white trim, pale oak, brushed nickel, and charcoal accents for a restrained blue-gray palette. It also makes a good choice for cabinetry or a painted ceiling when the surrounding walls are kept light and neutral.

LRV of Windy Blue
Windy Blue has an LRV of 47.51% and refers to Light Medium colors that reflect half of the incident 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 47.51%, 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.
