Dutch Tile Blue vs Marine

Both from Sherwin-Williams's palette. Dutch Tile Blue reads as blue-grey, while Marine reads as green-grey — two distinct hue families, not close cousins. Dutch Tile Blue (LRV 39) reflects noticeably more light than Marine (LRV 36), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 5.5 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
