Nocturne vs Sea Mariner

Both are Sherwin-Williams colors. Nocturne reads as greige-grey, while Sea Mariner reads as blue-grey — two distinct hue families, not close cousins. With LRVs of 8 and 7, they'll behave almost identically in terms of how much light they reflect back into a room. The tonal difference — Nocturne's warm character against Sea Mariner's cool — becomes most visible against white trim or in morning light. At ΔE 15.1, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions.
