Atmospheric vs Thames Fog Simulated Comparison
5 simulated room previews — drag the slider on each to see Atmospheric on one side and Thames Fog 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.
