What Colorize B/W does
Colorize B/W writes prompts that colourise with historical plausibility rather than a fantasy palette. The pack covers skin tone variation, period-accurate clothing and hair colour, foliage and sky, and the small detail most colourisers miss: keeping grain and tonal range so a colourised image still looks like a photograph.
Colourise portraits, family photographs and historical scenes
Apply period-plausible clothing, hair and skin tones
Handle mixed skin tones correctly in group photographs
Keep the original grain and tonal character rather than a flat modern look

Practical use cases
Colorize B/W earns its keep in real projects, not just experiments. A few workflows that work well:
Family albums and heirlooms. Colourise scanned family portraits with known clothing and hair colours supplied in the prompt, so the result matches what relatives remember rather than a generic tint.
Local history and archive projects. Bring period-plausible colour to street scenes, workshops and village photos for a community history page or a printed exhibition panel.
Book and article illustration. Colourise historical illustrations and documentary stills for an article or slide deck where a flat monochrome image would feel disconnected from modern visuals.
Selective colour for portraits. Keep the background monochrome and colour only the subject's face and clothing, a classic treatment for family portraits and memorial pieces.
Video frame restoration. Colourise frames of old home movies one by one with a locked palette, then reassemble the clip so the colour stays consistent across cuts.
Frequently asked questions
How accurate is AI colourisation?
It is an informed interpretation, not a record. Skin, sky and foliage are usually convincing; a specific persons eye or hair colour has to be told or guessed. The pack lets you supply known colours for clothing, hair and eyes.
Can I colourise just part of a photo, like the faces?
Yes. Selective colourisation is a common request for family portraits — the pack includes a variant that keeps the background monochrome and colours only specified subjects.
Is Colorize B/W free on PromptVault? Are there any limits?
Yes — free forever. Every PromptVault tool is free, with no subscription, no credit card, no trial, no account and no daily generation cap. You can use Colorize B/W as often as you like.
How do I keep the period look instead of a modern colour grade?
Describe the era and ask for muted, period-plausible tones: mention film stock or printing style, keep saturation conservative, and instruct the model to preserve the original grain. The pack includes period palettes for common decades so you do not have to guess the wording.
What should I do for group photos with mixed skin tones?
List the subjects separately in the prompt and give each a tonal hint, then tell the model not to apply one uniform tint to everyone. The pack has a group-photo variant that keeps each person's tone distinct, which is where generic colourisers usually fail.
Should I restore scratches first or colourise first?
Restore the physical damage first — remove scratches, dust and cracks while the image is still monochrome — then colourise. Repairing after colourisation can bleed colours across the fixed areas. The pack sequences the two passes for you.
