What colour should a passport photo background be?

Start with the country, not the wall

White is correct in some countries and banned outright in one of the most common. France says so in a single line: "Le fond doit être uni, de couleur claire (bleu clair ou gris clair par exemple). Le fond blanc est interdit" — plain, light-coloured, light blue or light grey for example, and a white background is forbidden. The United Kingdom asks for a photo taken against "a plain cream or light grey background", which is also not white. The Netherlands accepts three colours. Germany wants a single colour and prefers light grey. The United States wants white or off-white. So the wall is a per-country decision, and the one shade that will never be wrong everywhere does not exist.

What is close to universal is the second half of the rule, which most people skip past: the background has to be uniform. A single colour, no gradient, no shadow, no skirting board, no door frame, no light patch where a lamp hits it. That part fails far more photos than the wrong shade does, and it is the part you can fix by standing somewhere else.

What each authority asks for

"Plain" is a stricter word than it looks

The Dutch Fotomatrix spells out what everyone else implies. The background must be egaal and éénkleurig — even and one colour — and specifically without gradient or shadow. It goes further in the lighting section: the exposure must be even across the face and the background, with no shadow in either. GOV.UK phrases the same thing as no shadows on your face or behind you. Italy's guidance bans shadows and reflections behind the head.

Read together, that rules out several surfaces people reach for by instinct: a textured wall, an eggshell finish that catches a highlight, a corner where two planes meet at slightly different brightnesses, a shower curtain, a bedsheet with fold lines still in it. A bedsheet works only pressed flat and pinned taut, and a phone camera resolves creases you cannot see from across the room.

Contrast matters as much as colour

The Netherlands is explicit that there must be enough contrast between the head and the background, and says what happens when there is not: the picture prints faintly on the document. That is a practical constraint the colour rule does not give you. Pale blonde or grey hair against a white wall, or a white shirt against a white wall, leaves the outline of your head or shoulders with nothing to sit against. Light grey is easier to work with for that reason, and it is permitted almost everywhere in the table above except the United States and Spain.

The same logic runs the other way for clothing. Dark, plain clothing against a light wall reads cleanly. See what to wear for the parts that are actual rules — Ireland bans uniforms including insignia, and the United States bans uniforms and uniform-like clothing including camouflage.

Choosing a wall, and standing away from it

The single change that fixes most home backgrounds is distance. Stand with your back almost touching the wall and any light in the room throws a hard-edged shadow of your head and shoulders directly behind you, inside the crop. Move a metre or more forward and two things happen at once: the shadow falls further back and lower, often out of frame entirely, and what is left of it spreads and softens because the light reaching the wall is now arriving from a wider spread of angles.

A workable setup, in order:

1. Find the largest unbroken area of plain wall in the house, in the right colour for your country. Check the frame for a light switch, a socket, a skirting board or the edge of a door.
2. Stand a metre or more in front of it. This matters more than anything else on the list.
3. Face a window. Daylight from the front is broad, even and free of the colour cast that a warm bulb adds.
4. Turn the ceiling light off. Mixing a warm bulb overhead with cool daylight from the side puts two different colours on one wall, and a wall lit in two colours is not éénkleurig.
5. Have someone else hold the phone, roughly a metre and a half away, rear camera, no zoom, plain photo mode, flash off. Taking the photo with a phone covers the settings in detail.

Lighting the wall separately

If the wall still comes out darker than your face, or shaded on one side, the fix is to light it rather than to brighten the file afterwards. Anything soft and broad will do: a second window, a lamp with a shade bounced off the ceiling behind you, a work light aimed at the ceiling rather than at the wall. Point it at the wall directly from one side and you replace an even background with a bright patch and a falloff, which is worse than what you started with.

Two checks tell you whether it worked. Take a frame with nobody in it, look at the four corners, and see whether they match. Then take one with the subject in place and look along the edge of the head and shoulders for a dark rim. If the corners match and the rim is gone, the background is done. Lighting a passport photo without shadows goes through the harder cases.

Why not just replace the background

Because the authorities that publish an editing rule at all have written it against exactly that operation. GOV.UK requires the photo be "unaltered by computer software". Canada's list names background replacement outright, along with brightness, contrast, colour and sharpness corrections, filters and AI tools. The State Department says not to change the photo with "computer software, phone applications or filters, or artificial intelligence", and says it checks photos for AI use. Mexico does not accept retouched photographs. Ireland's online upload must not be digitally enhanced. The Dutch acceptance criteria list niet bewerkt — not edited — as a requirement in its own right.

There is also a plainer reason. A cut-out rarely survives contact with hair. The edge of a replaced background either eats a few strands or leaves a halo of the old wall around them, and a flat digital white has none of the gentle falloff a real wall has, so it reads as a cut-out at a glance. Cropping and resizing are a different matter: every authority specifies an outside size and a head height, and no photograph arrives at 29–34 mm in a 35 × 45 mm frame by itself. Where the line falls between cropping and retouching is the longer version of this argument.

Checking the background you actually got

Backgrounds fail in ways that are hard to see on a phone screen at arm's length — a gradient across the frame, a shadow that is obvious at print size, a corner a shade darker than the other three. The checker measures the background for evenness along with sharpness, exposure, lighting and resolution, and reports what it found rather than correcting it, which is the point. The UK, US, Canada and Schengen crops and the DS-160 upload all run in the browser tab, with nothing uploaded and no cap on how many times you try; the iOS app is free to download and gives one free export before it asks for Pro, so a session of retakes belongs on the web tool. If you are printing, the 4 × 6 sheet builder writes the real print density into the file. None of them can tell you a photo will be accepted — the issuing authority decides that.
