Foundation Shade Matching Guide
How to match foundation online: undertone first, then depth (fair to deep). Use AI skin tone analysis before buying.
Two-step matching
Professional artists match in two steps: (1) undertone — warm, cool, neutral, olive; (2) depth — how light or deep the skin reads. Most mismatches come from getting undertone wrong while depth is close.
Photo tips for online matching
Use natural window light, no filter, no SPF flashback, and a bare face. Match along the jaw — not the neck or forehead alone. Test three shades if possible: your guess, one lighter, one deeper.
- Avoid bathroom yellow lighting
- Remove heavy bronzer before analysis
- Check match in daylight after application
AI vs in-store
AI undertone tools narrow your shade family before you swatch in store or order online — reducing returns and wasted samples.
