S 7500-N vs Rockweed
Where S 7500-N belongs to NCS's range, Rockweed is a Sherwin-Williams color. These are both greys, so the question isn't which hue to choose — it's where within grey to land.

S 7500-N runs neutral while Rockweed is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of NaN, the contrast is hard to miss.
