Andes Summit vs River Rock

Andes Summit and River Rock come from the same Benjamin Moore collection. Hue-wise, Andes Summit belongs to the blue-grey family and River Rock to the beige-greige family. The 8-point LRV gap — 14 for Andes Summit vs 7 for River Rock — means Andes Summit will open up a space more effectively. Where Andes Summit leans blue, River Rock reads yellow — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 23.2 puts these firmly in different territory — two distinct design choices rather than close alternatives.
