Mystical Shade vs Proper Gray

Both are Sherwin-Williams colors. These are both greys, so the question isn't which hue to choose — it's where within grey to land. With LRVs of 40 and 40, they'll behave almost identically in terms of how much light they reflect back into a room. They share a neutral quality — useful to know if you're layering them in the same space. With a ΔE of 2.2, the difference is subtle — you'd need them side by side to reliably tell them apart.
