What color is Sherwin Williams Cosmos?
Sherwin Williams Cosmos SW 6528 is a muted, medium-light blue with a noticeable gray cast that keeps it from reading overly bright. Its cool blue character can look a little cleaner in daylight, while warmer bulbs may bring out the softened, silvery quality of the color. Cosmos is well suited to bedroom, bathroom, or home office walls where a calm but visible color is wanted. Pair it with crisp white trim, pale greige upholstery, weathered oak, or brushed nickel for a restrained, layered palette. It can also make a handsome choice for cabinetry or a painted interior door against lighter neutral walls.

LRV of Cosmos
Cosmos has an LRV of 37.91% 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 37.91%, 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.
