flagcat Colors

We've created a colorization engine to help our artists get through the tedious tasks faster, so they can concentrate on the creative ones.

How does it work?

How does it work?

Our artists can draw and save their character designs, and then use the engine to colorize the saved characters directly into the webtoon panels, on top of line art.


Thanks to this tool, we can automate the color filling and simple shading of character designs, normally done with ClipStudioPaint by clicking on all the areas to be colored. This gives our colorists more time for artistic tasks: retouching, backgrounds, complex shadows, special effects, etc.


This tool, similar in concept to already existing tools found in CSP and Photoshop, was developed in-house by our tech team, and is partly based on AI technologies, trained on our own character designs. The technology and renderings are therefore 100% proprietary, and are used solely to improve the daily work of our colorists.

Once our character designs have been drawn and validated, our artists upload them into our internal interface, and colors and simple shades are recorded by the engine.

Our colorists take care of colorizing the rest of the panel, placing complex shadows, setting the mood, adding special effects and backgrounds.

Q&A

What is the technology behind the Flagcat Colors?

We developed this tool internally, by combining AI and other technologies, trained on images drawn by our artists, 100% proprietary. On a feature standpoint, we consider Flagcat Colors as another tool to help artists colorize quicker, like Photoshop and Clip Studio Paint's Magic Wand. To elaborate on the comparison, both Flagcat Colors and Magic Wand are based on machine learning. While the former can reduce considerabily colorisation time and simple shadows, the latter makes it possible to smartly select a zone and colorize it in one click. These tools aim at helping artists daily work.

Is Flagcat Colors allowed by webtoon platforms?

Why did you build this tool?

Will you open the Flagcat Colors to others webtoon artists?
