What color is Sherwin Williams Sleepy Blue?
Sherwin Williams Sleepy Blue SW 6225 is a light, muted blue-gray with a distinctly cool cast and low-saturation appearance. Its soft gray influence keeps the blue from feeling bright or sugary, giving walls a quiet, airy look. In daylight, this shade can read as a clean pale blue, while lower or warmer lighting may bring its gray side forward. Sleepy Blue suits bedrooms, bathrooms, laundry rooms, and ceilings where a gentle wash of color is wanted without strong contrast. Pair it with crisp white trim, pale oak, weathered wood, brushed nickel, or charcoal accents for a calm, grounded palette.

What are Sherwin Williams Sleepy Blue undertones?
Sleepy Blue reads as a light, very muted blue-green with a soft gray cast and low saturation. In the supplied digital sample, the subtle color bias leans teal, meaning it sits between blue and green rather than reading as a clear sky blue. Sherwin-Williams identifies it simply as a blue paint color; the visible green influence is a relative observation from the sample, not an official undertone claim. Warm artificial light may make its gray-blue character appear a little softer or less crisp, while cool daylight can make the blue-green direction easier to notice.

LRV of Sleepy Blue
Sleepy Blue has an LRV of 57.75% and refers to Light colors that reflect most 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 57.75%, 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.
