The Paint Tool SAI bucket fill tool is a graphics editor made in Japan that is used to fill in sections of colouring. It works by selecting the area to be filled and then using the bucket tool to fill the selected area with colour. This tool is similar to other programs, but with a slight difference: it does not stop immediately when another colour is introduced. This can cause the colour to bleed into areas that were not intended to be filled. To avoid this, users can use a selection tool to ensure the colour only fills the desired area.
| Characteristics | Values |
|---|---|
| Filling the entire section | Use the selection wand to select the area you want to fill, then go to the top and hit selection -> dilate selection by... and make it so the blue selection pixels are just overlapping your lineart by 1-3 pixels. |
| Filling in sections with one colour | Use the magic wand tool to select outside the lineart, then invert the selection, and bucket fill the piece with a single basic colour. |
| Filling in sections with multiple colours | Outline the section with the colour you want to fill it in with, then use the bucket to fill that part in. |
| Dealing with teeny-tiny areas | Raise the Fill Bucket's threshold or use the Pen Tool. |
| Avoiding bleeding | Ensure the lines are fully connected. |

What You'll Learn

Using the magic wand tool to select outside your line art
The magic wand tool in Paint Tool SAI is a versatile selection tool with three detection modes: Transparency (Strict), Transparency (Fuzzy), and Color Difference. The Color Difference mode is the most useful, as it allows you to select areas based on colour. The "Color diff." bar lets you adjust how strict the colour selection is. This is particularly handy when you want to select a specific colour in a particular area.
To use the magic wand tool to select outside your line art, start by selecting the area outside your line art with the magic wand. Then, use the "Invert" function to invert the selection, ensuring the colour doesn't bleed through. This will leave you with a selection of your line art. To avoid any colour leakage, you can use the "Increment" tool a few times, causing the selection to bleed slightly into the line art. Inverting the selection again at this point will prevent colour bleed.
Once you have your line art selected, you can use the paint bucket tool to fill the selected area with colour. It is recommended to adjust the paint bucket settings to change the range of fill to avoid any pixelated white lines. Another method is to create a new layer, set the selection source to the line art, and then use the bucket tool on the new layer.
Additionally, you can use the "Layer -> Fill" shortcut, which defaults to Ctrl+Backspace, to fill the selected area with the foreground colour.

Inverting the selection and filling with a single colour
To start, select the Magic Wand tool and click on the area around your line art. The selected area will turn blue, indicating that it is in Select Mode. Don't forget to select the small areas outside your line art as well, as these may be missed by the Magic Wand tool. You can use the Selection Brush for this, which works just like the Pen Tool and allows you to "draw" the areas you want to select.
Once you have selected the areas you want, invert your selection. This can be done by going to the Toolbars, selecting "Selection", and choosing "Invert Selection". The blue selected areas will now turn into "marching ants", indicating that your selection has been inverted.
Now, create a new layer under your line art. This will be your base layer for your colour. Using the Fill Bucket tool, fill in this area with your chosen colour. You can then lock this layer to prevent any accidental changes.
Go to your line art layer and locate the Opacity Lock option. Click on the bubble next to it, which will turn the layer's box into an aqua colour. This indicates that this layer is now the Selection Source. With the Selection Source set, you can now use the Fill Bucket tool to fill in the selected areas with your chosen colour.
Another method for achieving the same result involves a slightly different approach. Instead of using the Magic Wand tool, you can use the Selection Wand tool to select the area you want to fill. Then, go to the top menu bar and select "Selection" -> "Dilate Selection" and adjust the settings so that the blue selection pixels overlap your line art by 1-3 pixels. After that, use the paint bucket tool to fill the selected area with your chosen colour.
By following these steps, you can invert the selection and fill it with a single colour in Paint Tool SAI, allowing you to create clean and precise colour fills for your digital art projects.

Using the selection wand to select the area you want to fill
The selection wand is a versatile tool that can be used in a variety of ways to select areas you want to fill with colour in Paint Tool SAI. The tool acts as a brush, allowing you to change its size, opacity, pen pressure, and even add texture.
To start, you can use the selection wand to select outside your line art. This creates a boundary for your colour filling. You can then invert the selection, so that only your line art is selected. This is a quick way to ensure that your colour stays within the desired lines.
The selection wand has three detection modes: Transparency (Strict), Transparency (Fuzzy), and Color Difference. The first two modes are useful for selecting transparent regions surrounded by lines, with the Fuzzy mode being ideal for roughly sketched images. The Color Difference mode is more versatile, allowing you to select regions based on their colour. You can adjust the "Color diff." bar to control how strict the colour selection is, making it easy to select specific coloured areas.
After making your selection with the wand, you can further adjust it by using the "Dilate Selection" feature. This allows you to expand or contract the selection by a few pixels, ensuring that it aligns perfectly with your line art.
Once you're happy with your selection, you can then use the paint bucket tool to fill the selected area with your chosen colour. By using the selection wand in conjunction with the paint bucket tool, you can achieve precise and controlled colour filling within your artwork.

Dilating the selection to overlap line art by 1-3 pixels
To dilate the selection to overlap line art by 1-3 pixels, follow these steps:
Firstly, use the magic wand tool to select the area you want to fill. This can also be done by using the selection wand and selecting the area you want to fill. Next, go to the top menu bar and click on 'Selection'. From the dropdown menu, select 'Dilate Selection By' and adjust the settings so that the blue selection pixels overlap your line art by 1-3 pixels. Click 'OK' and then use the paint bucket tool to fill the selected area with colour.
This method ensures that the paint bucket tool fills the entire section within the line art, without leaving any pixelated white lines or gaps. By dilating the selection, the paint bucket tool will fill the area, overlapping the line art by a few pixels, resulting in a more seamless and accurate fill.
It is important to note that this method may require some experimentation to achieve the desired results. The number of pixels you choose to overlap the line art may vary depending on the specific artwork and the size of the selection. It is always a good idea to create a new layer when trying out new tools or techniques, so you can easily adjust and refine your selection without affecting your original artwork.
Additionally, you can also try creating a new layer and clipping it to the base colour layer. Then, set the selection source to the line art and use the bucket tool on the new layer. This allows you to fill the selected area with colour while keeping the original line art intact. Experiment with different methods and settings to find the one that best suits your workflow and the specific requirements of your artwork.

Setting the selection source to the line art
To set the selection source to the line art, you can follow these steps: First, make a new layer after applying a base fill colour. Then, clip this new layer to the base colour. Next, set the selection source to the line art. Finally, use the bucket tool on the new layer to fill in the selected area with colour.
It's worth noting that the selection source setting is typically used for painting line drafts. Additionally, the magic wand and selpen tools have the same function as the selection group.
There are also other ways to achieve a similar effect. One method involves using the selection wand to select the area you want to fill, then going to "Selection" and choosing "Dilate Selection by..." This will cause the blue selection pixels to overlap your line art by 1-3 pixels. After hitting "Okay," you can then use the paint bucket to fill the selected area.
