River Rock vs Turtle Green

River Rock and Turtle Green come from the same Benjamin Moore collection. Hue-wise, River Rock belongs to the beige-greige family and Turtle Green to the beige-green family. The 6-point LRV gap — 13 for Turtle Green vs 7 for River Rock — means Turtle Green will open up a space more effectively. Both share a yellow character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 15.6 puts these firmly in different territory — two distinct design choices rather than close alternatives.
