Greyhound vs Cool Charcoal
Greyhound is a Behr color while Cool Charcoal comes from PPG. These are both greys, so the question isn't which hue to choose — it's where within grey to land. With LRVs of 21 and 20, they'll behave almost identically in terms of how much light they reflect back into a room. With a ΔE of 0.5, the difference is subtle — you'd need them side by side to reliably tell them apart.
