Sherwin Williams

Mild Blue

SW 6533

Mild Blue is a soft blue with subtle purple undertones and an LRV of 65, giving it solid light reflectance for bedrooms, bathrooms, and hallways. The lavender-leaning base distinguishes it from purely coastal or sky blues, adding a quiet coolness that reads cleanly on north-facing walls. It remains light enough for full-room application without overwhelming a space.

Compatible Sherwin-Williams pairings include Extra White (SW 7006) for trim, along with Intellectual Gray (SW 7045), Indigo Batik (SW 7602), City Loft (SW 7631), and Colonnade Gray (SW 7641).

Mild Blue in Different Light

Light temperature is measured in Kelvin: a warm 2700K bulb pulls colors toward yellow, while 5000K daylight reads cooler and truer. Check the color at the time of day you actually use the room.
