Welded Iron vs Up In Smoke
Welded Iron is a Behr color while Up In Smoke comes from PPG. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. With LRVs of 16 and 16, they'll behave almost identically in terms of how much light they reflect back into a room. With a ΔE of 1.0, the difference is subtle — you'd need them side by side to reliably tell them apart.
