About Flagstone
PPG Flagstone (PPG1001-4) LRV and undertone
PPG Flagstone (PPG1001-4) has an LRV of 41, placing it in the mid-tone range toward the darker end. Light reflectance value describes how much visible light a painted surface reflects. Compared with lighter grays, Flagstone reflects less light and may therefore appear deeper on walls, particularly in rooms with limited daylight. Its color family is gray, and its calculated undertone is neutral. The supplied analysis does not indicate a dominant warm yellow undertone. Nevertheless, surrounding colors and the type of illumination can influence how any gray appears. Cooler north-facing light may make gray surfaces look cooler, while warmer daylight or incandescent lighting can shift their perceived balance. Test the color beside existing flooring and trim to assess contrast.

Benjamin Moore Boothbay Gray (HC-165) has an LRV of 43.26 and a ΔE of 3.9, also a close match by the stated range. Benjamin Moore Coventry Gray (HC-169) measures LRV 48.18 and ΔE 4.2, making it similar rather than close. Valspar Granite Dust (5006-1C) has an LRV of 48.11 and a ΔE of 4.9. Sherwin-Williams Dorian Gray (SW 7017), at LRV 39 and ΔE 5.2, is another similar option. These comparisons account for measured color difference, not just brightness. As a result, a candidate with a similar LRV may still look different when placed directly beside Flagstone.
Lighter and darker PPG alternatives
PPG Whirlwind (PPG1013-3) has an LRV of 53, twelve points above Flagstone, and is the lighter same-brand alternative listed with the smallest ΔE of 5.2. PPG Ghost Writer (PPG1007-3), at LRV 48, is also lighter, with a ΔE of 6.0. Both offer greater light reflectance, although their measured color differences mean they are not close matches. For darker choices, PPG After the Storm (PPG1036-4) and PPG Stonehenge Greige (PPG1024-5) each have an LRV of 34. Their lower reflectance may suit rooms where a deeper wall color is wanted, while the latter belongs to the beige family with a warm yellow undertone. Use sample boards rather than small chips when comparing these alternatives, and observe them against trim in morning and evening light.
