How these matches are calculated
Every shade is mapped to a shared system: depth (1 = fairest, 10 = deepest) and undertone (Cool, Neutral, Warm, or Olive). The converter finds the NARS shade closest in depth, weighted 70%, and undertone compatibility, weighted 30%. It's the same engine behind our interactive matcher.
Two caveats: brands classify undertones differently (MAC's NC/NW runs opposite to most), and formulas oxidize differently — a matte formula can darken 1–2 levels over a few hours.
FAQ
How accurate is this Too Faced BTW to NARS conversion?
Each match is scored on depth (how light or dark) and undertone compatibility. Matches above 90% are usually very close; between 80–90% expect a slight difference in undertone or depth. Formula differences (matte vs dewy) and oxidation also affect how a shade looks on skin, so always swatch in natural daylight before buying full size.
