Lucky Shamrock vs Ionian
Lucky Shamrock is a Benjamin Moore color while Ionian comes from Sherwin-Williams. These are both blues, so the question isn't which hue to choose — it's where within blue to land. With LRVs of 18 and 20, they'll behave almost identically in terms of how much light they reflect back into a room. The tonal difference — Lucky Shamrock's green character against Ionian's cool — becomes most visible against white trim or in morning light. At ΔE 3.7, the difference is perceptible but not dramatic — the two can work harmoniously in the same space.
