News
- Style2Paints will be renamed into "SEPA" before 2022. The name "SEPA" is a short version of "StylE2PAints".
- We are actively developing SEPA (or called style2paints V5).
- SEPA has already been developed for two years, and it will be released before 2022.
- If you are interested, we have a twitter account here.
- Currently, only the source codes of V1, V2, and V3 are avaliable. We will release the source codes for the previous online version style2paints v4 and this offline version style2paints v4.5 when the project SEPA (previously called style2paints v5) is released, at which point the life cycle of style2paints 4.X is end.
- We have removed the shading functionality from style2paints V4.5 because some packages are incompatiable with the backend engine of V4.5 windows binary release. Project SEPA (previously called style2paints v5) has a much better backend engine and the shading functionality will come back in SEPA (style2paints v5).
- SEPA (style2paints v5) is scheduled to be released before 2022.
Currently, we recommend you to use style2paints V4.5 before Project SEPA is ready.

Welcome to style2paints V4!
Style2paints V4 is the current best AI driven lineart colorization tool.
Different from previous end-to-end image-to-image translation methods, style2paints V4 is the first system to colorize a lineart in real-life human workflow, and the outputs are layered.
Inputs:
● Linearts
● (with or without) Human hints
● (with or without) Color style reference images
● (with or without) Light location and color
Outputs:
● Automatic color flattening without lines (solid/flat/inherent/固有色/底色 color layer)
● Automatic color flattening with black lines
● Automatic colorization without lines
● Automatic colorization with black lines
● Automatic colorization with colored lines
● Automatic rendering (separated layer)
● Automatic rendered colorization
Style2paints V4 gives you results of the current highest quality. You are able to get separated layers from our system. These layers can be directly used in your painting workflow. Different from all previous AI driven colorization tools, our results are not single 'JPG/PNG' images, and in fact, our results are 'PSD' layers.

Help human in their standard coloring workflow!
Most human artists are familiar with this workflow:
sketching -> color filling/flattening -> gradients/details adding -> shading
And the corresponding layers are:
lineart layers + flat color layers + gradient layers + shading layers
Style2paints V4 is designed for this standard coloring workflow! In style2paints V4, you can automatically get separated results from each step!
Examples
Here we present some results in this ABCD format. Users only need to upload their sketch, select a style, and put a light source.
When the result is achieved immediately without any human color correction, we regard this result as fully automatic result. When the result needs some color correction, human can easily put some color hints on the canvas to guide the AI coloring process. In this case, we regard these results as semi-automatic results. If a result is semi-automatic, but the quantity of human color hint points is smaller than 10, we regard these results as almost automatic result. In this section, about half of the presented results are fully automatic result, and the others are all almost automatic result. Do notice that all the below results can be achieved with less than 15 clicks!
