It’s convenient to color each part separately, so that you will be able to easily change selections and use them as clippings later. At that time, it’s acceptable to use the Brush tool and the Eraser tool, but if there is an area enclosed by a line then you can fill it in completely with the Flood Fill tool.
An area like this that is enclosed in solid lines can be filled in using the Flood Fill tool. Next we’ll add a layer for an undercoat.
Open the layer window and tap the ①“＋” button to add a new layer for an undercoat. Next, tap the ②Added layer to make it active.
The undercoat layer is beneath the drawing. You may change the order of the layers by dragging the ①Thumbnail image.
Tap the Bucket button on the ①Tool Selection window and select the ②Flood Fill tool.
Tap the ① button to open the Flood Fill Properties window.
The fill will take the transparency level and color of the starting point and fill in everything with a solid color, including changes in color within the specified range. If you would like to use the line drawing layer as an edge then please select ②Opacity as the Edge. Also, if you would like to use the fill layer or a photo as the Edge then please select Color as the Edge. If you would like to use the illustration as the Edge then press ①Opacity here. The strength percentage determines the amount of color change from the start point will be included before it is considered an edge. If you select 0% then only the exact same color will be filled in. If you select 90% then, for example, if the starting point transparency is 100% then everything between 100% and 10% opacity will be filled in. If you select 100% then the entire layer will be filled in regardless of opacity. Here we will set the opacity to a ③Strength of 60%.
Next we will select the Current Layer to make it a Reference Layer and then fill in the Current layer.
When Specific layer is selected, the layer selected below becomes a reference layer and the Current layer is filled in. If Canvas is selected then the combined layers below are treated as reference layers and the Current layer is filled in. Here we want to use the line drawing as a reference and fill in the Current layer, so we select ④Specific layer, then tap the ⑤layer row and select the line drawing layer.
Select a color from the Color window. Here we select the ①Hue Thumb and ②Saturation Thumb and drag them to select a skin-tone color.
Now let’s fill in the skin color. Tapping inside the line drawing will fill in the entire area. If there are leaks or the entire layer is filled in then press the Undo button (Go back one step).
The figure above shows how the skin and shoe color has been changed with the Flood Fill tool.
The figure above shows the difference between a strength setting of 10% and 90%. You can see how a stronger setting leads to more area being filled in. If there are gaps between the fill and the lines then increase the strength as much as possible. Also, expantion it can decrease the number of gaps.
I believe it’s difficult to grasp the fill settings. We often hear people say, “I can’t use the Flood Fill tool because it is buggy. It always fills the entire canvas.” but if you don’t understand it yet, try setting the Edge to Color 10% and the Reference Layer to Canvas and you should achieve the desired results. Also, the Easy Settings often allow one to use the Flood Fill tool accurately, so if you don’t quite understand the setting yet then turning on “Easy Settings” may help.
After successfully filling in the layer window it will look like this when opened. ① is the line drawing layer, ② is the undercoat fill layer, and ③ is the rough sketch layer . Once the undercoat is complete you can easily turn that area into a Clipping Path or select it with the Magic Wand.
