Hair colour is the most reversible-looking decision in a salon and the most expensive to get wrong. A box dye that turns brassy, a bleach that lifts too far, a shade that looked warm on a swatch and cold under your bathroom light: all of it is avoidable if you can see the colour on your own face first.
This hair colour changer keeps the photograph intact and changes only the hair: the strands keep their light and shadow, the roots stay believable, and the skin, background and clothing are untouched. Twelve shades from jet black to platinum, balayage and a fantasy colour, with eyebrows left alone unless you say otherwise.
Why a flat colour fill never looks real
The difference between a colour filter and a believable dye is light. Real hair is not one colour: it is lighter where the light hits the crown, darker in the shadow behind the ear, and warmer at the ends where it is older and more porous. A flat fill loses all of that, which is why cheap hair-colour apps look like a wig.
The prompt on this page asks for the opposite: colour that follows the strands, respects the original light direction, and keeps a natural falloff. That is also why a photo taken in daylight previews better than one under a warm bulb, because the model can see the real light it has to preserve.
How to try a hair colour in three steps
- 1Upload a portrait with visible hairJPG, PNG or WEBP up to 4 MB, hair loose rather than tied back, daylight if possible. A photo where the hair fills a good part of the frame gives the model more to colour.
- 2Choose a shade and a finishNatural for a realistic preview of a salon colour, glossy for the salon-fresh look, subtle when you want to see a small shift rather than a transformation.
- 3Name what must stayKeep my roots darker, no colour on the beard, cherry red not orange. Then compare two shades side by side: judging one in isolation makes almost everything look plausible.
Shades and who they suit
| Shade | Undertone | Note |
|---|---|---|
| Jet black | Cool | Harsh on pale skin without warmth in the makeup |
| Dark brown | Neutral | The safest change from black, grows out invisibly |
| Chestnut | Warm | Adds light to the face, easy to maintain |
| Auburn | Warm red | Flattering on warm and olive skin |
| Copper | Bright warm | High maintenance, fades fast, striking in photos |
| Honey blonde | Warm | Needs lifting from dark hair, plan for two sessions |
| Platinum | Cool | Only from light hair, or expect real damage |
| Ash brown | Cool | Balances redness in the skin |
| Burgundy | Cool red | Reads rich indoors, dramatic in daylight |
| Grey | Neutral | Salt-and-pepper blends better than flat silver |
Taking the result to a colourist
A preview is a brief, not a formula. Colourists work in levels and tones, and the useful thing you can tell them is not the name of the shade but the direction: warmer or cooler, lighter by how much, and whether you want the roots to stay darker. Show the image, then describe the difference you want from it.
Two practical notes. First, if your hair is currently dark and the target is blonde, no preview can show you the intermediate stage, so ask for a two-step plan. Second, the same shade reads differently on different hair textures: straight hair shows tone, curly hair shows depth.
Free hair colour try-on vs a salon consultation
A consultation is still the right answer for a big change: a colourist can see your hair in person, feel its condition and tell you what is realistic. What a preview does is narrow the conversation before you sit in the chair, so you spend the appointment deciding between two directions instead of starting from nothing.
It is also useful for the opposite case: convincing yourself not to do something. Most people who preview a dramatic shade discover within thirty seconds that they like the idea more than the result, which is a cheap way to learn.
Credits, limits and honest failures
Each colour preview costs credits, priced per model and shown before you run, and new accounts start with free credits. Uploads are capped at 4 MB, output is 4:5 at up to 1344 pixels on the longest edge, and no watermark is added.
Where it fails: hair that is very dark against a dark background, hair in heavy shadow, and photos with a strong colour cast, because the model cannot separate the hair from the light. Fix the photo first with the enhancer if the cast is bad, then preview.
Maintenance, fading and the honest cost
Every shade fades. Warm reds and copper lose their intensity fastest, blonde drifts brassy over a few weeks, ash tones go dull, and black is the only shade that barely moves. If you are not prepared for a salon visit every six to eight weeks, choose a shade within two levels of your natural colour rather than fighting it.
Roots are the second cost. A colour that is lighter than your natural hair shows a regrowth line in about four weeks, which is why balayage and root-shadowed colours are so popular: they are designed to survive the grow-out. Preview both the shade and the practicality before you commit.
Colour and skin undertone, quickly
The shortcut colourists use is undertone: warm skin suits warm shades, cool skin suits cool or ash shades, and olive skin sits in between with the most flexibility. Getting that wrong is what makes a technically correct dye look like it belongs to someone else.
A one-minute test: look at the veins on your wrist in daylight. Blue-ish veins usually mean cool, green-ish mean warm, and a mix means neutral. If you are between two options, preview the cooler one first; cooler shades are easier to correct than warm ones that have gone brassy.
