Coverage caveat

The 12-season color framework was developed in a Western-Caucasian cosmetic context and refined for East Asian skin in the K-beauty 2010s. Other skin-tone reference data is thinner. Tonebook's read is robust across the full Fitzpatrick range, but we treat the model as a hypothesis you confirm in a mirror, not a verdict.
