Sherwin Williams

Secure Blue

SW 6508

Secure Blue is a moderately saturated cool blue with gray undertones and an LRV of 22, positioning it in the lower-middle range of light reflectance. It reads as a solid mid-dark blue in daylight and may appear more muted under warm artificial lighting. The gray undertone tempers its saturation, preventing it from reading as overly bright.

This color is commonly applied in bedrooms, home offices, and bathrooms. Secure Blue pairs with Sherwin-Williams Pure White for trim contrast, Greek Villa as a warmer white, Icicle for a lighter tonal blue, and Urbane Bronze for a warm accent.
