Deep River vs Grappa

Deep River and Grappa come from the same Benjamin Moore collection. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 8 vs 9 — so neither will read significantly brighter or darker than the other. Where Deep River leans green, Grappa reads purple — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 15.5 puts these firmly in different territory — two distinct design choices rather than close alternatives.
