Pencil Sketch vs S 3502-B
Pencil Sketch is a Behr color while S 3502-B comes from NCS. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. With LRVs of 33 and 35, they'll behave almost identically in terms of how much light they reflect back into a room. The tonal difference — Pencil Sketch's blue character against S 3502-B's neutral — becomes most visible against white trim or in morning light. With a ΔE of 1.5, the difference is subtle — you'd need them side by side to reliably tell them apart.
