How we verify dupes
Shade names lie; color math does not. Each foundation shade is converted to Lab color space and compared by ΔE (perceptual color distance): under 2 is near-identical, 2-4 reads the same on skin in normal light. We also require the undertone and depth to line up, because two shades with the same surface color can wear differently if the undertone underneath differs. Not sure of your own undertone?
