Perennial Grey vs Intellectual Gray
Perennial Grey (Little Greene) and Intellectual Gray (Sherwin-Williams) come from different manufacturers. Both sit in the greige-grey family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 38 vs 36 — so neither will read significantly brighter or darker than the other. Where Perennial Grey leans red, Intellectual Gray reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 3.5 means they're clearly different, but not dramatically so — they'd pair well in the same room.
