How to Colorize Old Black-and-White Photos
There is something magical about seeing a century-old black-and-white photograph suddenly burst into colour. It transforms a distant historical image into something immediate and personal — a great-grandparent becomes a real person, a vintage street scene feels like somewhere you could walk into, and faded memories regain their vibrancy. AI colorization makes this possible for anyone, for free, in just a few clicks.
How AI Colorization Works
AI photo colorization uses deep learning models trained on millions of colour photographs. The AI learns to recognise objects, textures, and scenes — it knows that skies are usually blue, grass is green, skin tones fall within certain ranges, and clothing colours follow predictable patterns. When you feed it a black-and-white photo, the AI analyses the grayscale values and intelligently assigns realistic colours to each region.
Modern colorization models go beyond simple colour washes. They can distinguish between different materials (fabric, metal, skin, wood), recognise lighting conditions (sunlight, shade, indoor), and even infer colours from context — like knowing that a military uniform from a specific era should be a particular shade of khaki or olive.
How to Colorize Photos Using BersihBG
- Visit the Photo Colorizer page on BersihBG.
- Upload your black-and-white or sepia photo. JPG, PNG, and WEBP formats are supported.
- Adjust the colour intensity slider. Higher values produce more vibrant, saturated colours. Start at 100% for most photos.
- Enable the Restore toggle if your photo has scratches, folds, or dust spots. The AI will denoise and reduce damage before colorizing.
- Optionally enter colour hints — e.g., "blue sky, green grass, red brick building, brown hair" — to guide the AI toward your preferred colour palette.
- Click Colorize Photo and wait 10-30 seconds for the AI to process. Download your newly coloured photo.
Tips for the Best Colorization Results
- Start with a clean scan: Scan or photograph your original photo at the highest resolution available. Clean scans give the AI more information to work with, resulting in more accurate colours.
- Use the Restore feature for damaged photos: Old photos often have scratches, dust spots, creases, and faded areas. Enable restore to let the AI clean up these defects before adding colour.
- Provide colour hints for accuracy: If you know what colours something should be (e.g., "grandma's dress was blue," "the car was red"), type these hints into the text field. This dramatically improves accuracy.
- Adjust intensity to taste: Some AI colorizations can look slightly washed out or overly vibrant. Use the intensity slider to dial in the perfect saturation level for your photo.
- Try different approaches: If the result does not look right, try again with different colour hints or adjust the intensity. AI colorization is an art as much as a science.
Use Cases for Photo Colorization
- Family history and genealogy: Bring ancestral portraits to life for family history projects, reunion presentations, and digital family albums. Colour makes historical figures feel relatable and real.
- Historical preservation: Museums, historical societies, and archivists use AI colorization to make historical photographs more engaging for modern audiences in exhibitions and online collections.
- Wedding and event photography: Restore and colourise vintage wedding photos that were originally shot in black and white, creating beautiful heirloom-quality images.
- Creative projects: Artists and designers use colorized vintage photos as unique source material for collages, album covers, posters, and social media content with a nostalgic aesthetic.
- Educational materials: Teachers and publishers colourise historical images to make textbooks and educational resources more engaging for students.

How accurate are the colours produced by AI colorization?
AI colorization is remarkably accurate for common scenes and objects — skies, vegetation, skin tones, and typical clothing. For ambiguous subjects (unusual objects, specific historical uniforms, or brand colours), providing colour hints helps the AI produce more accurate results.
Can I colorize sepia-toned photos?
Yes. The AI recognises sepia-toned images and handles them well. The tool works on black-and-white, sepia, and even faded colour photographs that need restoration.
How long does colorization take?
Most images are processed in 10-30 seconds. The first ever request may take up to a minute as the AI server initialises. Larger images take proportionally longer.
Do I need an account to use the colorizer?
Yes, because the colorization runs on our AI servers, a free account is required. Free users receive daily AI credits, and VIP subscribers get unlimited colorization with priority processing.
