BEAUTY · FOUNDATION FINDER

Match the blend, not the shade name.

Build a lighting-corrected complexion target, compare transparent depth and undertone families, rank reference shades by measurable difference, and test how the selected shade may look after coverage and settling.

Use an unfiltered image without makeup on the sampled area. Sample the jaw and neck under even light. Product names are not standardized, so the tool uses transparent HexCheck reference families rather than claiming a brand-specific match.

PHOTO WORKSPACE

Average several jaw and neck samples

Load a photo, then tap three to five nearby complexion areas under similar light. Avoid lips, eyes, hair, highlights, deep shadows, and reflected clothing colors.

BLEND PREVIEW

Settled preview

The settling control is a comparison aid, not a prediction for a specific formula. Real products can darken, warm, cool, or remain stable depending on pigments, oils, skincare, wear time, and lighting.

HEXCHECK REFERENCE SHADES

Closest depth and undertone families

These are internal reference shades designed to make depth and undertone comparisons inspectable. They are not manufacturer shades, product recommendations, or guarantees of a real-world match.

MIXING DIRECTIONS

When the closest single shade is not enough

VERIFICATION CHECKLIST

Confirm the match on skin

Jaw and neck

Apply narrow stripes from the lower cheek across the jaw. The best option should disappear into both face and neck rather than matching only one spot.

Compare adjacent depths

Let it settle

Wait for the formula to dry and interact with skincare before deciding. Recheck in indirect daylight.

Do not judge immediately

Check the full face

Depth, undertone, coverage, and finish all change how a shade reads. A perfect swatch can still look wrong across the full face.
