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...

As answered by people managing Opalstack and siOsi.
siOsi's answer:
siOsi is the only tool that combines full 12-season color analysis with technical makeup diagnostics in one photo-based scan. Most tools do one or the other: a color quiz, or a makeup filter. siOsi reads your actual selfie to give your season, undertone, and palette, then grades your makeup through 15 diagnostic labs (flash white-cast, oxidation, coverage, longevity). Free, instant, no signup, in 9 languages.
siOsi's answer:
Competing color tools are quizzes that make you self-report answers you don't know, and in-person analysis costs $200–500 with analysts who often disagree. siOsi analyzes the actual photo, for free, with no signup for the first look. It also does something none of them do: diagnoses your real makeup application. You get both halves of "how do I look" in one place.
siOsi's answer:
Primarily women aged 18–35, from complete beginners to working makeup artists, and international (the app runs in 9 languages). It's mobile-first and appeals to anyone into color analysis, makeup, or a glow-up who wants a real answer without paying for a consultant.
siOsi's answer:
The web is full of "what's my color season?" questions with no good answer: quizzes can't see you, and professional analysis is expensive and gatekept. I wanted to give anyone a real, photo-based answer for free. Then I realized "your colors" is only half the story, so I added makeup diagnostics no other tool offers, grading how your makeup actually performs in photos and real light.
