Brittany Blue vs Mt. Rainier Gray
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. With LRVs of 61 and 59, they'll behave almost identically in terms of how much light they reflect back into a room. They share a blue quality — useful to know if you're layering them in the same space. With a ΔE of 2.4, the difference is subtle — you'd need them side by side to reliably tell them apart.
