In our daily life, sometimes we will encounter the need of coloring pictures, such as turning old black and white photos into color photos, or painting our own drawn line drawings into color drawings. In fact, it is very difficult to color a picture manually, professionals can color it a little bit through professional software such as Photoshop, while for us ordinary users who don’t know art, we can use the online service provided by Style2Paints to finish coloring automatically.
First of all, we prepare an original to be colored, then open https://s2p.moe, click on the “Upload” button, and follow the instructions to upload the original to the web page (Figure 1). Note that since the service is free of charge, the server has a limit on the number of users online, so if you are prompted with too many users, please wait until other online users quit before you can use the service.

After successful upload, you can see a canvas similar to the drawing on the web page, in order to achieve a better automatic coloring effect, here you can drag the adjustment slider in order to adjust, here pay attention to try not to have too much blank area on the canvas, the first operation try to choose a smaller area (such as half body image is easier to color than full body image) click OK after finishing the selection (Figure 2).

You can see that the website has built in many AI painter settings, the operation of coloring is very simple, we just need to simply click on the right panel, the original will be automatically finished coloring, you can see the speed of coloring is very fast, and the effect is also more professional (Figure 3).

Tip: There are two modes in the built-in coloring effect, which are.
Careful mode (careful mode), select this mode after the artificial intelligence will be carefully applied smooth, color effect is more fine, but the artificial intelligence in this mode will limit the play of self, and can not automatically get the best results, it is recommended that veterans use this mode, you can do more manual processing in the post.
Careless mode (careless mode), artificial intelligence will play on their own, but may be lost in detail, but for ordinary users, this coloring effect is sufficient, it is recommended that newcomers choose to use.
After finishing the automatic coloring, if you check the details of the coloring, you can scroll the mouse to zoom the coloring picture, and move the picture by clicking the gesture icon, so that we can view each coloring part in detail (Figure 4).

Of course, in practice, we may not be satisfied with the automatic coloring effect, and we can make more fine-tuning operations on the coloring result to make the final coloring effect reach our expectation.
1. Local color fine-tuning
For users who want to improve, we need to fine-tune the color of subtle parts after AI finishes coloring. At this time, you can click the area that needs to be fine-tuned in the coloring picture, then a small rectangle area will be added in the selected area, and click the color that needs to be fine-tuned in the color panel on the right side as prompted (in order to ensure the overall effect, it is recommended to choose the color that is roughly the same as the original color here). To facilitate comparison of the before and after effects, you can always click on the square icon above to view the base color (Figure 5).

2. Adding local light and shadow
In the coloring operation, we can add light and shadow effects to certain areas in order to highlight them, and the Style2Paints online service can also add this effect to areas. For example, if we need to add light and shadow to the face of a person, click on the Add Light icon (rendering icon) at the top of the website, then click on the circle icon at the bottom, click on the area of the face where you want to add light and shadow, and select the x icon to delete the marked area. At this time, light adjustment parameters will appear on the right side of the website, from top to bottom, the light source color RGB brightness, light source position and brightness adjustment parameters, pull different sliders to fine-tune as prompted (Figure 7).
