Great Grape vs Old Mill Blue
Great Grape and Old Mill Blue come from the same PPG collection. Both sit in the blue-grey family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 16 vs 17 — so neither will read significantly brighter or darker than the other. ΔE 3.1 means they're clearly different, but not dramatically so — they'd pair well in the same room.
