Sienna vs Thames Fog

The 17-point LRV gap — 27 for Thames Fog vs 10 for Sienna — means Thames Fog will open up a space more effectively. A ΔE of 36.8 puts these firmly in different territory — two distinct design choices rather than close alternatives.

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.
