Rapid Rock vs Thin Ice
Rapid Rock and Thin Ice come from the same PPG collection. Rapid Rock reads as beige-greige, while Thin Ice reads as grey — two distinct hue families, not close cousins. The 40-point LRV gap — 70 for Thin Ice vs 30 for Rapid Rock — means Thin Ice will open up a space more effectively. A ΔE of 28.6 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

5 simulated room previews — drag the slider on each to see Rapid Rock on one side and Thin Ice on the other.
Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
