Charcoal Blue vs Grey Splendor
Charcoal Blue is a Behr color while Grey Splendor comes from Dulux. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. With LRVs of 19 and 21, they'll behave almost identically in terms of how much light they reflect back into a room. The tonal difference — Charcoal Blue's blue character against Grey Splendor's neutral — becomes most visible against white trim or in morning light. With a ΔE of 1.5, the difference is subtle — you'd need them side by side to reliably tell them apart.
