Passport Photo Color Requirements 2026 – sRGB, Resolution, and Print Standards
Most photo rejections due to colour are caused by incorrect white balance or low print resolution. Here is the complete technical picture: colour space, DPI, common casts, and paper type.
Short answer
ICAO requires natural skin tone reproduction in sRGB colour space. Minimum 600 DPI for printing (300 DPI is not sufficient). Digital files: minimum ~827×1063px for 35×45mm at 600 DPI. Background: pure white (#FFFFFF or very close). Use glossy or satin paper only — not matte. Colour casts from tungsten lighting are the most common home photo problem.
sRGB vs CMYK: Which Colour Space for Passport Photos
Passport photos should always use the sRGB colour space. ICAO Doc 9303 and virtually all national authority digital submission portals expect sRGB JPEG files.
CMYK (Cyan, Magenta, Yellow, Black) is a subtractive colour model used in professional offset printing and some desktop publishing workflows. A JPEG file saved in CMYK will:
- Display with incorrect (often darker and more saturated) colours on screen
- Be rejected by many online passport photo submission portals
- Produce colour shifts when printed on inkjet printers that expect sRGB
Good news: standard smartphone camera photos and JPEG files saved from most photo editing applications (Lightroom, Snapseed, GIMP) are already in sRGB by default. The CMYK issue typically only arises if you export from a CMYK workflow in Photoshop or InDesign.
Resolution Requirements: DPI and Pixel Dimensions
Resolution determines how sharp and detailed your printed photo appears. For a biometric passport photo, the standard is:
- Minimum for printing: 600 DPI at the final print size. At 600 DPI, 35×45mm requires approximately 827×1063 pixels.
- Recommended: 1200 DPI or higher, which corresponds to approximately 1654×2126 pixels for a 35×45mm photo.
- 300 DPI is insufficient for photo-quality passport prints. At 300 DPI, 35×45mm is only 413×531 pixels — visibly soft when enlarged to print size.
- Digital submission only: Many online portals accept files as small as 600×800px, but check the specific portal requirements.
An important caution: artificially upscaling a low-resolution image to meet pixel count requirements does not improve real resolution. It creates a high-pixel-count file that prints with the same blurry quality as the original. Start with a high-resolution source file.
Background Colour: What “White” Really Means
ICAO specifies a “plain white or off-white” background. In practice, the acceptable range is approximately:
- Pure white: #FFFFFF (RGB 255, 255, 255) — acceptable for all ICAO-standard countries
- Off-white: Very slightly warm or cool white, approximately RGB 245–255 across all channels — acceptable in most countries
- Light grey: Only acceptable for France's national ID card (CNI) and for some countries that specify “light grey.” Not suitable as a universal default.
- Cream, beige, or yellow-tinted: Not acceptable — indicates a colour cast from warm lighting on a white background
A pure white background photographed under warm incandescent lighting will appear cream or yellow in the photo. This is a very common home photo problem. The solution is either to use daylight-balanced lighting, correct the white balance in editing, or use an AI tool that replaces the background with pure digital white.
Common Colour Problems, Causes, and Fixes
| Problem | Cause | Fix |
|---|---|---|
| Orange/warm cast on face and background | Tungsten bulb lighting (standard incandescent) | Use window light or set white balance to "Tungsten" / correct in editing |
| Blue cast, cold-looking skin tones | Shade, overcast sky, or cold-white LED without warming | Move to direct window light or set white balance to "Cloudy" |
| Green cast on skin and background | Fluorescent ceiling lighting | Avoid fluorescent rooms; use window light or correct with white balance |
| Uneven skin tones, shadow on one side | Off-axis single light source (desk lamp to one side) | Use diffused front lighting or two light sources either side |
| Background appears cream or yellow instead of white | White wall photographed under warm artificial light | Correct white balance, or use AI background replacement to pure white |
| Washed-out, overexposed skin tones | Direct flash too close, or overexposed in bright light | Move back from flash, use bounce flash, or avoid direct sunlight |
| Muddy, desaturated colours | CMYK colour profile applied to JPEG before printing | Convert to sRGB before saving or submitting |
| Pixelated or blurry print | Image file below 600 DPI at print size | Use higher resolution source image; avoid upscaling |
Always verify current requirements with the official issuing authority before submitting.
Print Paper: Glossy, Satin, or Matte?
Passport photos must be printed on glossy or satin photo paper only. Matte paper is not acceptable for the following reasons:
- Matte paper absorbs ink, reducing apparent sharpness and fine detail compared to glossy or satin stock.
- Many biometric document scanners are calibrated for the reflective properties of glossy photo stock. Matte paper can produce inconsistent optical scan results.
- Several national authorities explicitly require photo paper (Fotopapier / papier photographique) — which in practice means glossy or satin.
Between glossy and satin: both are generally acceptable. Satin (sometimes called semi-gloss or pearl) is often preferred as it is less prone to fingerprint marks and handling damage, while still meeting reflectivity standards. For critical applications, a dedicated photo lab guarantees calibrated output on the correct paper stock.
How ID Wizard Ensures Correct Colour Output
ID Wizard processes uploaded photos through several colour-related quality checks:
- Background replacement: The AI replaces detected backgrounds with pure digital white (#FFFFFF), eliminating lighting-induced colour casts on the background.
- sRGB output: All output files are rendered in sRGB colour space, compatible with digital submission portals and standard photo lab printers.
- Resolution: Output files are generated at the correct pixel dimensions for the selected country format, meeting minimum resolution requirements for print submission.
- Print layout: The print download includes a correctly formatted sheet (4 photos on 10×15cm) at the appropriate DPI for glossy photo paper printing.
Frequently Asked Questions
Should a passport photo use sRGB or CMYK colour space?
Passport photos should use the sRGB colour space, not CMYK. ICAO Doc 9303 and most national authority digital submission portals expect sRGB JPEG files. Standard smartphone camera photos and JPEG files are already in sRGB by default.
What is the minimum resolution for a passport photo?
For printing, the minimum recommended resolution is 600 DPI at the final print size of 35×45mm, corresponding to approximately 827×1063 pixels. 300 DPI is insufficient for passport photo print quality. For digital submission only, check the specific portal requirements — typically 600×800px minimum.
What colour cast is most common in home passport photos and why?
The most common colour casts in home photos: orange/warm cast from tungsten bulb lighting; blue cast from shade or cold LED lighting; green cast from fluorescent lighting. All can be corrected by using natural window light or setting the correct white balance on your camera.
Can I print a passport photo at home or should I use a photo lab?
You can print at home with a colour-accurate inkjet printer on glossy or satin photo paper at minimum 600 DPI. Matte paper is not acceptable. For important applications, a dedicated photo lab guarantees the correct paper stock and calibrated colour output and is lower risk.
Always verify current requirements with the official issuing authority in your country before submitting a passport application.
