The 12-season system starts from the four familiar seasons and splits each by its dominant quality. Winters are cool and deep: Deep Winter (dark hair and eyes, high contrast — carries black and true jewel tones effortlessly), Cool Winter (blue-based, icy clarity) and Bright Winter (high contrast plus unusual brightness — the rare people who wear true fuchsia well). Summers are cool and soft: Cool Summer (rose-toned, medium contrast), Soft Summer (muted, greyed coloring that harsh brights overwhelm) and Light Summer (fair, low contrast, best in powdery pastels).
Autumns are warm and rich: Deep Autumn (dark, warm, earthy — chocolate, forest, burgundy), Warm Autumn (golden through and through — rust, olive, camel) and Soft Autumn (warm but muted — the season most often misdiagnosed as "no color suits me," when the real answer is that clear brights are the problem and softened earth tones are the solution). Springs are warm and clear: Light Spring (fair and delicate — ivory, peach, soft aqua), Warm Spring (golden and fresh — coral, warm turquoise) and Bright Spring (warm with startling clarity — poppy red, bright warm green).
Notice what the system is really encoding: three axes — warm versus cool, light versus deep, clear versus muted — and which one dominates you. That is why the analysis here reports undertone and contrast separately before naming your season. If you know you are warm-toned, low-contrast and muted, then even when two adjacent seasons are plausible (Soft Autumn versus Soft Summer is a classic borderline), you understand what actually matters when you hold a garment up to your face: keep it soft, keep it warm-leaning, skip anything icy or neon.
