How this color analysis works
The tool finds your face in the photo and samples the colors of your skin, hair, eyes and lips. From those colors it estimates three things that seasonal color analysis is built on: whether your undertone is warm or cool, whether your overall coloring is light or deep, and whether clear, vivid colors or soft, muted colors suit you better. Those three axes point to one of the four seasons and a closer sub-type. Answering the optional questions about your veins, jewelry and how you tan makes the result more reliable.
How to take a good photo for color analysis
Use natural daylight from a window, facing the light, and avoid yellow indoor bulbs, colored LEDs and direct harsh sun. Take the photo without a beauty filter or skin-smoothing mode, and with little or no makeup. Pull your hair back if it covers your face, and avoid strongly colored clothes right under your chin, since they reflect onto your skin. A plain, light background works best.
Use the result as a guide
Cameras, lighting and screens all shift colors, so a photo can never be as accurate as an in-person draping session with a color consultant. Treat your result as a starting point: try the suggested colors near your face in a mirror, use the drape test to compare two colors side by side, and trust what makes your skin look clear and even.
