What color is Sherwin Williams Mild Blue?
Sherwin Williams Mild Blue SW 6533 is a pale, muted blue with a noticeable gray cast that keeps it soft rather than sugary or bright. Its light value can make a room feel open, while the cool blue-gray character gives white trim a crisp contrast. In daylight, Mild Blue reads clean and airy; under warmer bulbs, its gray side may become more apparent. It suits bedrooms, bathrooms, laundry rooms, and ceiling treatments, especially alongside white oak, brushed nickel, linen fabrics, and warm white finishes. Pair it with charcoal accents for definition or sandy beige and putty tones to bring in a little warmth.

LRV of Mild Blue
Mild Blue has an LRV of 65.45% 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 65.45%, 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.
