Foundation Shade Selection Guide

Why Foundation Shade Matters

The wrong foundation shade creates a visible line between face and neck, or makes skin look ashy or unnaturally pale. The right shade evens out your complexion while maintaining a natural finish.

Understanding Foundation Undertones

Foundation shades combine depth (brightness level) with undertone.

• Warm (W / Yellow) — Yellow-toned warmth
• Cool (C / Pink) — Pink-toned coolness
• Neutral (N) — Between warm and cool

Shade Depth Numbers

• Fair / Light (13–15) — Very light skin.
• Light-Medium (20–25) — Slightly lighter than average.
• Medium (30–35) — Average skin tone range.
• Tan / Medium-Deep (40–45) — Deeper, olive, or golden tones.
• Deep (50+) — Rich, dark complexions.

• MAC NC — "Neutral Cool" actually means warm undertone. NC15 = light warm, NC42 = medium-deep warm.
• MAC NW — "Neutral Warm" actually means cool undertone.
• NARS — Uses name + depth number (e.g., "Deauville" Light 4).

Seasonal Adjustments

Skin color shifts with seasons. Go half to one shade deeper in summer after tanning, and lighter in winter. Always test in natural daylight for the most accurate match.

AI Foundation Matching

Choosing from dozens of depth-and-undertone combinations is tough. Lumi Tone uses skin tone analysis and Delta-E color difference algorithms to find the closest foundation match for you.
