What color is Sherwin Williams Honest Blue?
Sherwin Williams Honest Blue SW 6520 is a light, softened blue with a noticeable gray cast that keeps it from reading sugary or overly bright. Its cool blue character can appear a little cleaner in daylight, while lower or warmer light tends to bring out its muted, silvery quality. This color has enough depth for full-room walls in a bedroom, bathroom, or home office without making the space feel heavy. Pair Honest Blue with crisp white trim, pale oak, brushed nickel, and soft gray textiles for a restrained, airy palette. It also makes a gentle choice for painted cabinetry or a front door when surrounded by neutral siding and white architectural details.

LRV of Honest Blue
Honest Blue has an LRV of 54.87% 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 54.87%, 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.
