What Does the Skin Tone Finder Measure?
The Skin Tone Finder analyzes two essential factors: skin depth (lightness to deepness of your skin) and undertone (the subtle hue beneath your skin surface). Both are crucial for accurate foundation matching. The tool runs in your browser - your photo never leaves your device.
Skin Depth vs. Undertone: What’s the Difference?
- Depth: Ranges from fair to very deep; it describes how light or dark your skin is.
- Undertone: Can be cool, neutral, warm, olive, or golden. It’s the consistent color underneath your skin, unaffected by tanning or redness.
Many people confuse these. Depth is about shade; undertone is about hue.
How Brands Name Foundation Shades
Foundation shades are usually labeled with a number (for depth) and a letter (for undertone):
- N = Neutral
- W = Warm
- C = Cool
- G = Golden
- O = Olive
Your result will help you find the right shade code in most brands.
How to Scan and Read Your Result
- Use natural daylight (not indoor lighting or HDR mode) for your selfie.
- Follow the tool's prompts to scan your face in the browser.
- The tool will show your depth (e.g., medium-deep) and undertone (e.g., olive).
Once you have your result, use our Foundation Shade Matcher or browse undertone × depth lists at /foundation-for to see exact shade matches for popular brands. For deeper analysis, the Makeup Check AI app offers 24 AI reports, personalized looks, and tutorials.
