Photo analysis

Your photo is analysed in memory and never written to disk. Only the three extracted colours are stored — the image itself is discarded as soon as the analysis finishes.

For a usable reading

Face an even, indirect daylight source — a window, not direct sun.
No makeup on the forehead and cheeks if you can manage it.
Remove glasses, tie hair back from the face, and use a plain background.
Turn off warm indoor bulbs — they add an amber cast that reads as warm undertone.
Fill the frame with your face, looking straight at the camera.

{# capture="user" opens the front camera directly on a phone, including inside the Capacitor shells, so there is no separate camera code path to maintain. #}

If the result looks wrong, retake the photo in better light rather than accepting it — a bad sample produces a confident wrong answer.
