Cast Iron vs Mesmerize
Both are Sherwin-Williams colors. Cast Iron reads as grey, while Mesmerize reads as blue-grey — two distinct hue families, not close cousins. With LRVs of 13 and 13, they'll behave almost identically in terms of how much light they reflect back into a room. The tonal difference — Cast Iron's neutral character against Mesmerize's cool — becomes most visible against white trim or in morning light. At ΔE 19.5, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions.
