Sherwin Williams

Vast Sky

SW 6506

Vast Sky is a light cool blue from Sherwin-Williams with gray undertones that keep it from reading overly saturated. It has an LRV of 55, placing it in the mid-range where it reflects a moderate amount of light without appearing washed out. The hex value #A9C9D7 confirms its position as a muted, dusty blue.

This color works well in bedrooms, bathrooms, and open living areas where a cool-toned wall color is needed. It coordinates with Sherwin-Williams Alabaster for trim, Shoji White for ceilings, Misty for adjacent walls, Debonair as a deeper accent, and Tradewind for a tonal layered approach.
