Use the color bucket if we want to quickly fill an area with a color or a gradient.

This tool has the watercolor option.

Options

The color bucket comes with a few customizable options.

Contiguous

If the Contiguous option is on, only pixels that are contiguous (connected) to the original pixel will be affected, if it's off, it will affect all pixels on the entire canvas regardless of whether they are connected.

Tolerance

Adjust the Tolerance to allow "wiggling room", meaning that if the 2 colors are within the tolerance range, they will be counted as an identical color.

  • RGB: It will compare the RGB channel values

  • Indexed: It will compare the indices in the palette

Fill modes

Solid color

This mode will simply use the current color to fill, nothing special.

Linear gradient

This will fill the area with a linear gradient. After adding the anchor colors, drag the pencil from the start point to the endpoint of the gradient.

  • RGB: RGB values will be interpolated.

  • Indexed: The palette indices will be interpolated.

Linear gradient also has the "Perfect angle" option which will snap the angle to increments of 45 degrees

Radial gradient

Sampling mode

There are 3 modes for sampling.

Selected layer

This is the default mode for the color bucket tool. In this mode, it simply uses the content of the selected layer to fill.

Sampling layer

This is also called the referencing layer in some other software.

When turned on, a box will appear, we can long-press drag a layer (from the layer panel) to this box to make it the active sampling layer. Once set, the color bucket tool will use the active sampling layer to determine fill boundaries instead of the selected color in the layer panel.

This is particularly useful when we want to separate the outline and the color layers.

Visible layers

In this mode, anything that is visible on the canvas will be used at the sampling content.

Tolerance will behave differently in different :

We can also select to use dithering instead of a smooth interpolation.

For the no-dithering option, the colors between the selected colors are different in different :

The same as the , except that it's radial instead of linear. The center of the gradient will be the start coordinate.
