Where this color can work

Flagstone provides a medium gray anchor for a bedroom, mudroom, office, or cabinetry scheme that needs visible depth without approaching charcoal. Its balanced direction can work with both warm wood and cool metal, though the proportions of each matter. Shadowed walls will look considerably deeper. Try a full-size board behind furniture and near trim, and assess the finish under raking light, which can make a medium gray reveal wall texture and roller marks.

FAQ

Questions about Flagstone

How light or dark is Flagstone?

The listed LRV is 41.0. Higher LRV values reflect more light, but room exposure and finish still affect how open or deep the color appears.

Why are three cross-brand choices shown?

Small source-value differences can change the order of near neighbors. Three candidates create a practical sampling shortlist without claiming a guaranteed one-to-one conversion.

Can a store color-match Flagstone from this page?

Use the original PPG code PPG1001-4 when possible. The displayed hex and RGB values are screen references and should not replace a physical sample or store formula. In this library, the nearest cross-brand screen value is Castlerock DE6375 by Dunn-Edwards at ΔE 1.021.
