Free · one selfie · 12 seasons
Color analysis, minus the $300 appointment. Upload one selfie and siOsi reads your undertone, depth, and contrast, then drops you into one of 12 color seasons with the palette that actually makes you look awake. No quiz, no guessing, no cap.
What color analysis actually is
Color analysis finds the colors that flatter you based on your skin’s undertone, depth, clarity, and contrast, then sorts you into one of 12 seasonal color types and builds your personal palette. Wear your palette and your face reads brighter and more rested. Wear the wrong one and it quietly drains you.
siOsi reads three things straight from your photo:
- Hue
- Warm or cool — the yellow-vs-blue lean of your skin.
- Value
- Light or deep — how much contrast you carry.
- Chroma
- Soft or bright — muted and dusty, or clear and saturated.
The 12 color seasons
Four families, each split three ways by depth and clarity. Real siOsi palettes — the exact colors we’d hand you.
Winter
Cool Winter
Cool, clear, a little regal. Blue-based everything.
Deep Winter
Dark and saturated. Drama is the whole point.
Spring
Bright Spring
Warmth turned all the way up. Playful, punchy, loud.
Warm Spring
Golden-hour energy. Sunlit, toasty, alive.
Light Spring
Soft warm pastels. Delicate but never shy.
Summer
Light Summer
Cool and airy. Dusty pastels that whisper.
Cool Summer
Muted and cool. Understated, quietly expensive.
Soft Summer
Hazy, low-contrast. Smoke and soft mauve.
Autumn
Soft Autumn
Earthy and muted. Warm neutrals, no harsh edges.
Warm Autumn
Spice-rack rich. Rust, gold, terracotta.
Deep Autumn
Deep and warm. Chocolate, forest, ember.

How to find your undertone
Undertone is the single biggest driver of your season, and no single home test nails it on its own. Run a few together:
- Wrist veinsBlue or purple reads cool. Green reads warm.
- Gold vs silverWhichever metal makes your skin glow points to your undertone.
- White vs creamPure white flatters cool skin; cream flatters warm.
- Sun reactionBurn-then-fade leans cool; tan-easily leans warm.
When the tests disagree (they will), that’s where a photo read wins — siOsi weighs all the signals at once for a warm, cool, or neutral verdict.
Where color analysis comes from
Sixty years of figuring out which colors flatter people — from a Bauhaus classroom to a Seoul studio. The short version.
1961Johannes IttenThe Art of Color
At the Bauhaus, painter Johannes Itten noticed his students kept reaching for the colors that matched their own complexion. He called it "subjective color" and tied it to the four seasons — the seed the whole field grew from. He was the theorist, not the practical system.
“the aura of the person”
Johannes Itten, The Art of Color (1961) 
1978Bernice KentnerColor Me a Season
Kentner turned Itten's seasonal idea into something regular people — and the cosmetics counter — could actually use, two years before the book that made it famous.
1980Suzanne CaygillColor: The Essence of You
Caygill split each season into dozens of descriptive sub-types and turned the one-on-one color consultation into a real craft.
1980Carole JacksonColor Me Beautiful
The one that went mainstream. Four seasons for everyone, still in its 31st printing by 1983. It put "what’s my season?" into everyday language.
“Because it is difficult to print the color swatches 100 percent accurately … verbal descriptions will help you understand the concept of your colors when you shop for clothes.”
Carole Jackson, Color Me Beautiful (1980) 
1990s–2020sKathryn Kalisz → SeoulKathryn Kalisz's Sci\ART method refined the four seasons into 12 tones using color science — hue, value, chroma. Decades later, Korea's personal-color studios and social-media draping videos made the whole thing global again.
“Most people have predominantly yellow undertones in the skin — not pink as many people think. It’s safest, when choosing a foundation, to err on the yellow or golden side, not the blue-pink side.”
Color analysis, answered
What is color analysis?
Color analysis identifies which colors flatter you based on your skin's undertone, depth, clarity, and contrast. It sorts people into 12 seasonal color types (like True Autumn or Cool Summer) and produces a personal palette. siOsi does it free from one selfie in seconds — no questionnaire, no appointment.
What color season am I?
Your season depends on three traits: hue (warm or cool), value (light or deep), and chroma (soft or bright). Together they place you in one of 12 seasons. Upload a selfie to siOsi and its colorimetry engine reads all three and names your season instantly, free.
How do I find my undertone?
Use several tests together: check wrist veins (blue or purple reads cool, green reads warm), whether gold or silver jewelry flatters you, how you look in pure white vs cream, and how your skin reacts to sun. Single tests mislead — siOsi reads your undertone from a photo for an accurate consensus.
Am I a warm or cool undertone?
Warm undertones lean yellow, peach, or golden and suit gold jewelry and ivory. Cool undertones lean pink, red, or blue and suit silver and pure white. Neutral is a mix. If the tests disagree, upload a selfie to siOsi for a precise warm, cool, or neutral reading in seconds.
Gold or silver — which suits me?
Hold gold and silver near your face in natural light. If gold is flattering and your skin glows, you likely have a warm undertone; if silver flatters and brightens, you lean cool; if both look good, you are neutral. It is a quick undertone check, and siOsi confirms it automatically from your photo.
Is free AI color analysis accurate?
Professional in-person analysis costs $200–$800 (virtual $50–$169+). AI tools like siOsi are free and read undertone, depth, and contrast from a selfie in seconds. Accuracy depends on a good, unfiltered, natural-light photo — avoid beauty-app filters and heavy makeup, which distort the reading.
What are the 12 color seasons?
The 12 seasons expand the four (Spring, Summer, Autumn, Winter) by depth and clarity: Bright, Warm, and Light Spring; Light, Cool, and Soft Summer; Soft, Warm, and Deep Autumn; Bright, Cool, and Deep Winter. Each has a distinct palette. siOsi maps your selfie to one of these 12 automatically.
What colors make me look washed out?
Colors that clash with your undertone, or that match your skin's depth too closely, drain your face — often muted or overly warm/cool shades against the wrong season. Wearing your season's palette instead adds contrast and glow. siOsi shows which colors flatter you and which to avoid.
Does siOsi analyze makeup too?
Yes. Beyond color season and undertone, siOsi runs 15 makeup labs from the same selfie — foundation match, flashback, oxidation, coverage, blending, longevity, and more — each with a confidence score. It is color analysis plus makeup diagnostics in one free tool, which most color-analysis apps do not offer.
Do filters or makeup affect the result?
Yes — beauty-app filters, heavy makeup, and colored lighting distort undertone and skin depth, throwing off the reading. For the most accurate color analysis, upload a clean, well-lit, natural-light selfie. siOsi flags low-confidence photos so you know when to retake.
