About PPG / Glidden Flagstone
Flagstone sits in the mid-range at LRV 42, so it shifts visibly through the day — lighter and more open in morning light, deeper and moodier after dark. Because it carries almost no measurable hue, it stays a true neutral and pairs cleanly with nearly any trim or floor. South-facing rooms will pull it lighter and warmer, while north light cools it down.
Flagstone is versatile enough for full rooms but has enough depth to anchor a space, so it suits living rooms, bedrooms and cabinetry alike. Grays like this read as a modern neutral and sit comfortably alongside both warm woods and cool metals.
