The drape test you can do with clothes you own, plus what the ITA° number from a face tool adds to it.
Color seasons classify your skin's warmth, depth and clarity to predict which colour families harmonise. The classic test uses fabric drapes; a face tool adds the objective ITA° reading (skin-tone angle) on top.
The drape test decides direction (Spring/Summer/Autumn/Winter); the depth axis splits each family into three (Light/True/Deep, or Bright/Soft variants). Disagreements between drape and tool usually trace to photo lighting — redo the lighting guide.
It is a stylistics framework, not a measurement — but the underlying axes (warmth, depth, clarity) map to real colour parameters, and ITA° is a measurable skin value. Treat the season as a practical shopping shortcut, not a diagnosis.
