Comet vs Rocky Beach

Comet and Rocky Beach come from the same Benjamin Moore collection. Comet reads as blue-grey, while Rocky Beach reads as beige-greige — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 36 vs 38 — so neither will read significantly brighter or darker than the other. Where Comet leans blue, Rocky Beach reads red — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 19.7 puts these firmly in different territory — two distinct design choices rather than close alternatives.
