The system groups colours by warmth, value, and intensity, then matches them to your natural colouring. Warm, golden undertones lean Spring or Autumn; cool undertones lean Summer or Winter. Wearing your palette makes your complexion look brighter and more even.
It's the foundation for choosing flattering colours in colour blocking, monochrome looks, and a capsule palette — and the surest way to know is to see the shades against your own face.
