Granite Dust vs River Rock
Where Granite Dust belongs to Behr's range, River Rock is a PPG color. These are both beige-greiges, so the question isn't which hue to choose — it's where within beige-greige to land. They have nearly identical light reflectance values (63 vs 62), so they'll read as similarly Light in most lighting conditions. At ΔE 0.9, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.
