siOsi is a free AI tool that turns a single selfie into a complete color and makeup analysis — no signup, no quiz, no expensive consultant.
The problem: figuring out your colors today means one of two bad options. A five-question quiz can't actually see you, so it just guesses. And a professional in-person color analysis costs $200–500, with two analysts often giving two different verdicts. Neither is accessible, and neither looks at your actual face.
siOsi reads your real photo instead. Upload one selfie and it returns:
- Your 12-season color type (Warm Autumn, Light Summer, Deep Winter, and so on)
- Your undertone and contrast level
- A gold vs silver verdict — which metals and jewelry suit you
- Hair-color harmony and recommended shades
- A personal palette: the exact colors that flatter you, and the ones that wash you out
Then siOsi does something no other color tool does: it analyzes your makeup. Upload a made-up look and it grades your application through 15 diagnostic labs — flash white-cast (why foundation ghosts in flash photos), oxidation, coverage balance, longevity, crease and transfer risk, shimmer placement, and more. It also detects your face, lip, and eyelid shape and gives makeup guidance tailored to each.
How it works: siOsi combines vision models with facial-landmark detection to read skin, hair, and eye color, undertone, and contrast, maps them to the 12-season system, and scores the match — all in about 60 seconds.
Use cases:
- Find your color season without paying for a consultant
- Settle the gold-vs-silver question for good
- Build a wardrobe and makeup palette that actually flatters you
- Check whether your foundation flashes white or oxidizes before you post
- Choose a hair color that harmonizes with your features
- Shop smarter by carrying your palette with you
Pricing: a free tier with no signup for your first analysis, plus Pro ($9.99/month) for unlimited analyses and all 15 makeup labs.
siOsi runs on the web, and is fully localized in 9 languages. Photos are processed only for the analysis — never sold or used to train models. Try it free at siosi.me
