Make a free guide with your paintsMatches are computed by converting each paint's color to CIELAB and measuring CIE76 deltaE distance. A “great match” (deltaE < 3) is very close to the eye; a “close match” is a usable substitute. Finish, opacity, and coverage still differ between brands, so test on primer when it matters.
