Depth, undertone and contrast

The three signals that decide your color season. Read all three correctly and the palette is determined — it isn't up to personal preference.

Why three signals, not one

The classic four-season system (Spring, Summer, Autumn, Winter) split everyone along one axis: warm versus cool. It worked for maybe a third of the population. The modern 12-season system — developed by Sci\ART and refined by colorists like Christine Scaman — uses three independent axes, so every person's type is a combination of all three.

The result: Cool Summer and Soft Summer are both cool, both low-contrast — but one wears clear pastels and one wears dusty muted tones. They aren't interchangeable. Same warm/cool reading, different depth and contrast answers.

1. Depth — how light or dark you read overall

Depth is the combined value of your hair, skin, and eyes. Don't evaluate them one at a time — squint at yourself in a mirror and ask: am I generally light, medium, or deep?

• Light — blonde or very light brown hair, fair skin, light eyes. Think Nicole Kidman, Reese Witherspoon, a Light Summer or Light Spring.
• Medium — medium brown or warm auburn hair, medium skin, hazel or mid-tone eyes. Most of the Springs and most Cool/Soft Summers sit here.
• Deep — dark brown or black hair, any skin, dark eyes. Deep Autumns, Deep Winters, and many Clear Winters.

Common mistake: over-indexing on dyed hair. If your natural hair is medium but you color it platinum, your depth is still medium — the right palette is for your face, not your current box-dye.

2. Undertone — the warmth of your skin

Undertone is the colour your skin is underneath, regardless of how tanned, pale, or flushed you are on a given day. Cool undertones have pink, rose, or blue hints; warm undertones have peach, golden, or yellow hints; neutral undertones balance in between.

Three quick tests — we cover these in detail in how to find your undertone:

• Veins: blue/purple = cool, green = warm, mixed = neutral.
• Jewelry: silver flatters cool, gold flatters warm, both work on neutral.
• White paper: hold white near your face; rosy reflection = cool, peachy = warm.

Common mistake: confusing a tan for warm undertone. A cool-undertoned person who tans can look warm on the surface but their true undertone is unchanged. Test in a spot the sun doesn't reach (inner wrist, inside upper arm).

3. Contrast — how different your features are from each other

Contrast is the jump between hair, skin, and eyes. A dark-haired person with fair skin and light eyes has high contrast. A blonde with blonde eyebrows, light skin, and pale eyes has low contrast. Most people are medium.

• Low contrast: everything blends — your palette should do the same (soft, tonal, no sharp edges). Soft Summers and Soft Autumns live here.
• Medium contrast: features are distinct but not stark. Most of the warm/cool seasons.
• High contrast: features clash — dark against light, or electric colour against neutral. Clear Winters, Clear Springs, and some Deep Winters.

Common mistake: treating contrast as "am I allowed to wear black and white?" It's not a rule about the clothes — it's a description of your face. If you're low-contrast, wearing high-contrast outfits (like crisp black-and-white) makes your features look washed out by comparison. You want the outfit's contrast to match your face's contrast.

Putting all three together

Every one of the 12 seasons is one specific answer across all three axes. Soft Summer, for example, is: medium depth + cool-neutral undertone + low contrast. There's no other season with that combination. Get any one of the three readings wrong and you'll land in an adjacent palette — close enough to look fine, far enough to look subtly off.

This is also why season quizzes based only on hair colour (or only on undertone) give unreliable answers — they're reading one axis out of three.

What the AI analyzer does differently

A colorist trained in Sci\ART reads all three simultaneously from your face. Our AI analyzer does the same: it looks at the combined value of hair, skin, and eyes (depth), the warmth balance of your skin confirmed against your hair and eyes (undertone), and the value difference between them (contrast) — then matches the combination to one of the 12 seasons.

It's not a replacement for an in-person draping session with real fabric, but for 95% of people it lands the right season on the first try, and it gives a reader-friendly explanation of why.
