siOsi is AI color + makeup analysis from a single selfie — free, instant, no signup.

Color analysis today gives you two bad options: a 5-question quiz that can't actually see you, or a $200–500 in-person session where two analysts often disagree. siOsi reads your actual photo instead.

From one photo you get:

- Your 12-season color type (Warm Autumn, Light Summer, Deep Winter…)

- Undertone, contrast, and a season-match score

- Gold vs silver — which metals actually suit you

- Hair-color harmony and recommended shades

- A personal palette: the exact colors that flatter you, and the ones to avoid

What no other tool does — 15 makeup diagnostic labs:

Upload a makeup look and siOsi grades it like a lab: flash white-cast (why foundation ghosts in photos), oxidation, coverage balance, longevity, crease and transfer risk, and more — plus face, lip, and eyelid shape detection with tailored guidance.

Results in ~60 seconds, in 9 languages, on web and mobile. Free tier with no signup for your first analysis; Pro unlocks unlimited looks and every lab.
