Get your color season.
Explore a suggested season, undertone direction, and a 12-color starter palette from one photo. This is AI-assisted styling guidance, not a validated measurement or a guarantee of accuracy.
What is 12-season color analysis? It places natural coloring into one of 12 seasonal categories — three each within Spring, Summer, Autumn, and Winter — based on undertone (warm/cool), value (light/deep), and chroma (bright/soft). Each season is associated with a palette used as style guidance rather than scientific proof.

Your photo leaves this browser for analysis. It is resized here, then sent through Tonebook's Vercel service to OpenAI. Tonebook does not add this upload to a photo library. Provider retention is separate: read the privacy details before continuing. You can use the photo-free quiz instead.

How the AI color analysis works
Select a photo, review the preview, then choose analysis. Your browser redraws the image at a smaller size before sending it through Tonebook's Vercel endpoint to OpenAI. The model returns color suggestions; it does not establish a biological classification. No account or email is required. Provider retention is separate from Tonebook's handling of the request; see the privacy policy and OpenAI's data controls.
Take or upload a selfie
Use a well-lit, makeup-free selfie facing a window or natural light. Avoid strong overhead light, colored bulbs, or heavy filters — they shift the read.
Let the AI analyze it
After you choose analysis, the resized image is sent through Tonebook's Vercel service to OpenAI. Read the privacy details before continuing; this is not an on-device-only analysis.
Get your season and palette
You'll get your most likely 12-season placement, your undertone, and a 12-color starter palette to try immediately.
What is 12-season color analysis?
12-season color analysis places your natural coloring into one of 12 seasonal categories based on hue (warm/cool undertone), value (light/deep), and chroma (bright/soft contrast). Each season has a matching color palette for clothing and makeup.
How accurate is AI color analysis from a single photo?
The tool has not established a validated accuracy rate. Lighting, camera processing, makeup and framing can change the suggestion. The displayed model confidence is not a verified probability of correctness. This browser tool returns one suggested season; adjacent-season guidance is a separate iPhone app feature.
Is my photo stored?
Tonebook does not add this upload to a photo library. The image is handled by our Vercel endpoint and OpenAI, whose processing and retention rules are separate. Do not assume that an upload is immediately deleted from every provider system. See the privacy policy before uploading.
What's the difference between this tool and the Tonebook app?
This free web tool gives you a directional season and starter palette from one photo. The Tonebook iOS app adds a 12-season result with confidence guidance, a fuller palette, a wardrobe closet, daily outfit matching, and hair/makeup guidance.
