Questions, answered.

Your color season is where your skin, hair, and eyes sit across four measured axes — undertone (warm to cool), depth (light to deep), clarity (soft to bright), and contrast — scored against the twelve seasons. Callume's free read names it from one photo in about fifteen seconds; the full session measures it against a reference in the frame for a calibrated answer.

Photo-based color analysis tops out around 75 to 85 percent agreement with an in-person analyst, so Callume caps its stated confidence at 95 percent on purpose — a tool claiming certainty is telling you something about itself. Every axis in the reading carries an error bar, and every facial measurement carries a reliability tier.

Because most read the color your camera guessed, not the color that was actually there. The same face photographed under a warm bulb and again in cool daylight comes back as two different seasons. Callume corrects the light against a known reference in the frame first, so the answer holds still.

No. A sheet of plain white printer paper works as the reference — hold it under your chin and the phone walks you through the shots. If you would rather not fetch anything at all, your phone can use its own screen as the light instead. A real 18% gray card is still the most exacting option and Callume will use one if you own it, but nothing about a full session requires you to buy anything. The free read uses no reference at all, which is why it shows a lower, honest confidence.

The free read names your season and face shape from three selfies, honestly labeled, in about fifteen seconds. The full session adds calibrated color, all twelve seasons scored in CIELAB with hex and L*a*b* values, a 478-point facial-structure read, error bars on every axis, and a bound PDF you can re-download for a year.

An in-person studio analysis runs about 150 to 800 dollars; app subscriptions run roughly 13 to 260 dollars a year; one-time apps are 7 to 10 dollars. Callume is 39 dollars, paid once at the end of the session, with no subscription — and it is refunded if the analysis fails or the document never reaches you.

At the end, not the start. The full session runs free — the photos, the calibration, the drape rounds — and finishes with your verdict bound into a sealed document. Opening that document costs 39 dollars, once. Stop at any point before then and you pay nothing.

Yes. The free read wipes your selfies the moment it finishes. For a full session, your uploaded photos and the face geometry taken from them are deleted within 72 hours; only your styling read and PDF are kept, for up to a year, so you can re-download them. Nothing that can re-identify your face stays on the server past that.

Your photos are treated as biometric data under laws like Illinois's BIPA and the GDPR: processed only after you consent, only to generate your color and styling read, never used for face recognition, and never sold. Everything runs on one server we operate — no cloud AI service ever receives your photos.

A trained analyst in the room, with drapes and daylight, is still the gold standard for the drape step, and Callume says so. What a photo-based tool can add is measurement: white balance corrected to D65 against a known reference, color read in CIELAB, and confidence you can see. Callume is 39 dollars once instead of 150 to 800, and it hands you the numbers, not just a label.

Like all photo-based color analysis, Callume may not be equally accurate across every skin tone — we tune and test for this, but can't promise identical precision for everyone. A melanin index cross-checks depth so it is not confused with undertone, and every reading states its own uncertainty rather than hiding it.

No, and it never will be. Callume reads your coloring and facial structure to suggest styling — colors and shapes that complement you. There is no score out of ten; the measurements are neutral numbers used only for styling, not a judgment of your face.
