What PetalicaPaint is
PetalicaPaint is a free online tool that colours line art automatically. You upload a sketch, choose a colouring style and optionally add colour hints to steer specific areas, and the system fills in the rest. It is described as an assistant for artistic creation rather than a replacement for it, and it also offers a painting and doodling mode for looser experimentation. The service is provided by Preferred Networks and runs in the browser, so there is nothing to install.
What you can do with it
- Upload a hand-drawn sketch and colour it automatically
- Switch between colouring styles such as Japanese or French romantic
- Add partial colour hints to guide the result
- Doodle and paint directly in the browser
Who it is for
- Comic and manga artists who need flats before shading
- Illustrators testing palettes on a finished line drawing
- Hobbyists who want a quick coloured version of a sketch
What to watch out for
Input quality drives output quality. A clean, closed line drawing colours far better than a rough sketch with broken or sketchy lines, so scan or trace carefully first. The result is flat colour, not finished rendering, so shading, highlights and texture are still your job. Colour hints help but they do not give you precise control over every region. Free availability and the list of colouring styles can change, and there is no guarantee that a particular style will suit a particular drawing. Generated suggestions are for reference only, so verify anything that affects professional judgment or important data. Start with a small sample to confirm the output meets your expectations before processing the full batch.
