How to confirm the match
- Swatch on the jawline, not the wrist, and check in daylight.
- Match depth first, then undertone - a shade one step lighter/darker with the right undertone beats a perfect depth with the wrong cast.
- Let it sit 5-10 minutes: many formulas oxidise a touch darker/warmer.
Not sure of your own undertone or depth? Run the free undertone test or the skin tone finder - it reads them from a selfie in your browser (nothing is uploaded) - then come back to the matching shades.
How this works: shade colours are the brands' published swatches, converted to CIE Lab and compared with ΔE (colour distance). Swatches are approximations - lighting, formula finish, oxidation and skin chemistry all shift how a foundation reads. Use these as a shortlist and verify on your jawline in daylight.
