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.
