Seattle Mist vs RAL 850-1
Seattle Mist is a Benjamin Moore color while RAL 850-1 comes from RAL Effect. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. With LRVs of 55 and 53, they'll behave almost identically in terms of how much light they reflect back into a room. With a ΔE of 2.7, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Seattle Mist vs RAL 850-1 in Real Spaces
1 real room side by side. Seattle Mist and RAL 850-1 are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.

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.
