Things people build with this

USE CASE 1

Automatically colorize black-and-white sketches and line art into full-color illustrations with minimal manual input.

USE CASE 2

Generate separate color, gradient, and shading layers that can be imported and edited in Photoshop or other image editors.

USE CASE 3

Batch process multiple sketches using a consistent style reference to maintain a cohesive color palette across a series.

USE CASE 4

Explore different color palettes for a single sketch by providing different style reference images.

In plain English

Style2Paints is an AI-powered tool for automatically adding color to line art drawings. Unlike earlier AI colorization approaches that produce a single image output, Style2Paints is designed to match the layered workflow that illustrators and digital artists actually use: sketch, flat color fill, gradient and detail pass, and shading. The system can produce each of those stages as separate layers, which can then be opened and edited directly in image editing software. To colorize a sketch, you provide the line art and optionally a style reference image to influence the color palette, a few color hint points placed on the canvas, and a light source direction and color. The AI then produces flat color layers, a colorized version with and without the line art, colored line variants, and a rendered shading layer. According to the readme, about half of typical results are fully automatic (no hints needed) and most others require fewer than ten color hint clicks. The tool was presented at SIGGRAPH Asia 2018 and is available as downloadable software for Windows. Multiple versions exist (V4, V4.5, and a preview of V5), with the most recent complete release being V4.5. It does not require the user to install any programming environment, it runs like a normal application.

Copy-paste prompts

Prompt 1

I have a line art sketch I want to colorize. How do I use Style2Paints to add color automatically and get editable layers?

Prompt 2

Show me how to place color hint points on my sketch in Style2Paints to guide the AI toward the colors I want.

Prompt 3

Can I use a reference image to make Style2Paints match a specific color style when colorizing my artwork?

Prompt 4

How do I export the separate flat color, gradient, and shading layers from Style2Paints into Photoshop for further editing?

Prompt 5

What's the difference between Style2Paints V4.5 and V5, and which version should I download for my Windows computer?
