Example prompt: Can you colorize this black-and-white manga page for me? Here's the image URL: https://example.com/manga-page.png — please use a vibrant shonen action style.

## When to prefer this

Choose this endpoint when you need to quickly colorize a black-and-white manga or comic page using an AI model without setting up a local pipeline. It is ideal for previewing colored versions of manga art, prototyping colorization workflows, or adding color to public domain or original manga images. Not suitable when pixel-perfect or officially licensed colorization is required, since colors are AI-generated guesses.

## Known failure modes

- Image URL is not publicly accessible or returns a non-200 response
- Image exceeds the 4 MB size limit
- Image is not PNG or JPEG format
- Style prompt is outside the 3–200 character length range
- Workers AI model fails to process the image
- Network timeout or Cloudflare Workers infrastructure error

## How this service works

Colors a black-and-white manga page you name (public image URL, PNG or JPEG up to 4 MB) with a Workers AI image-to-image model. Output is a generated image, not the original artwork; colors are model guesses.

## Output

A generated color image of the submitted black-and-white manga page, produced by a Workers AI image-to-image model. Colors are AI-inferred guesses and may not match any official colorization. The output is a new generated image file, not the original artwork.
