Paints Chainer is a semi-automatic line drawing colorizer that uses convolutional neural networks built on the Chainer deep learning framework to colorize sketches. It includes a web-based UI for uploading line drawings and a Python server, along with training scripts and pre-trained models.

Use cases

  • colorize line drawings and sketches semi-automatically
  • add color hints to black-and-white manga or anime-style line art
  • run a local web server to colorize sketches through a browser UI
  • train custom colorization models on your own line art dataset
  • experiment with CNN-based image colorization using Chainer

When to choose

  • you want to automatically colorize anime or manga style line drawings with minimal manual effort
  • you need a self-hosted sketch colorization tool with a browser-based interface
  • you want to study or modify a CNN-based colorization pipeline with training scripts included

When to avoid

  • you need actively maintained software or support for modern deep learning frameworks
  • you require a production-ready colorization service with commercial licensing for the models
  • you work without an NVIDIA GPU or CUDA environment, since GPU support is central to its performance
