Autonomous vs Thames Fog
Autonomous is a Sherwin-Williams color while Thames Fog comes from Valspar. These are both greys, so the question isn't which hue to choose — it's where within grey to land. At LRV 57 vs 27, Autonomous will read as the brighter of the two — a 29-point gap that matters most in north-facing or low-light rooms. At ΔE 21.9, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions.

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.
