Gradient Types

Paint Bucket (G)

Fill an area of similar color with the foreground color or a pattern. Respects the tolerance setting to determine which pixels to fill.

1. Press G and cycle to Paint Bucket (Shift+G or options bar).
2. Set tolerance in the options bar (0-255).
3. Click on the area to fill.

Fill with Solid Color

Fill the entire layer or selection with a solid color using the Edit → Fill command.

1. Make a selection (optional -- fills entire layer if no selection).
2. Go to Edit → Fill, or press Shift+F5.
3. Choose foreground color, background color, or a custom color.
4. Set blend mode and opacity for the fill.
5. Click OK to apply.

Fill Within Selection

When a selection is active, fill operations are constrained to the selected area. This applies to both the Fill command and the Paint Bucket tool.

Clear Pixels

Delete the pixels within the current selection. On a normal layer, this sets the area to transparent. On a Background layer, it fills with the background color.

1. Make a selection.
2. Press Delete or go to Edit → Clear.
