siOsi

Color analysis today means 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: 12-season color type, undertone, gold vs silver, hair-color skintone harmony. Free, instant, no signup. Then it does what no other tool does — runs your makeup through 15 diagnostic labs: flash white-cast, foundation oxidation, coverage, longevity. 9 languages. No signup for your first analysis.
