Fog (#E3F4FA) by Behr is a very light blue paint color with a rich, saturated presence that draws the eye. It delivers an airy, open feeling that maximizes the sense of space in any room. On the temperature spectrum this shade carries a cool cast, lending calm and collected elegance. Its RGB channels are closely balanced, contributing to its neutral, even-keeled visual character.

A barely-there blue like this soothes bedrooms, ceilings, and nurseries with its sky-like openness. An eggshell or matte finish works well at this lightness, hiding minor wall imperfections while still being easy to wipe clean. For color coordination, Fog pairs beautifully with orange tones for bold complementary contrast, or with neighboring blue and teal hues for a harmonious, flowing palette. Its neutral undertone means trim and ceiling whites should lean neutral to avoid a jarring clash.

High-LRV colors like Fog are forgiving in most lighting conditions, but they can pick up reflected color from adjacent walls, flooring, or large furniture pieces, so evaluate samples in situ. Very light shades can sometimes read as stark white on small swatches — viewing a larger area in your intended space reveals the true character of the color.
