Korean personal color analysis (퍼스널 컬러 진단) finds the colors that actually work with your skin, hair, and eyes. Not the colors you like. The ones that make your face look alive instead of tired. It started from seasonal color theory and grew into a 4-season, 12-tone system that Korea runs on.
Four seasons: Spring, Summer, Autumn, Winter. Spring and Autumn suit warm undertones. Summer and Winter suit cool ones. Simple so far. The Korean twist is subdivision. Each season splits into subtypes (Light, Bright, Soft, Deep, Warm, Cool), giving you 12 or more distinct profiles instead of four broad buckets.
In Korea, this isn't niche. Professional color labs in Seoul book out weeks ahead. The diagnosis has become a cultural ritual, something friends do together, content for variety shows, a standard step before overhauling your wardrobe or makeup bag. The trend spread globally through K-beauty content, and now "what's your personal color?" is a question you'll hear at Korean dinner parties.
The Color Code tool on this site does a browser-based version. Upload a photo or use your camera. It samples your skin, hair, and eye colors locally on your device to determine your seasonal type. No upload, no server, no sign-up. You get your season, your undertone, and a palette of colors that flatter you.
