Celtic Blue vs Manor Blue
Both are Benjamin Moore colors. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. At LRV 47 vs 0, Manor Blue will read as the brighter of the two — a 47-point gap that matters most in north-facing or low-light rooms. The tonal difference — Celtic Blue's cool character against Manor Blue's blue — becomes most visible against white trim or in morning light. With a ΔE of 1.4, the difference is subtle — you'd need them side by side to reliably tell them apart.
