RAL 840-2 vs Grey Heron
RAL 840-2 is a RAL Effect color while Grey Heron comes from Sherwin-Williams. 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 66 and 65, they'll behave almost identically in terms of how much light they reflect back into a room. With a ΔE of 1.3, the difference is subtle — you'd need them side by side to reliably tell them apart.
