Filling areas with colors, gradients, or patterns

You can fill a selection or a layer with the foreground or background color, gradient, or pattern. You can fill all pixels or fill only those pixels that match the options you specify. When you click in the image, the Flood Fill tool finds and fills all contiguous pixels that match the pixel you select.

Contiguous pixels are like continuous chains of matching pixels radiating from the initial pixel you click. When the Flood Fill tool finds a pixel that does not match the selected pixels, the chain breaks. Even if a pixel is only one pixel away from a matching pixel, it is treated as discontiguous.

What is the difference between the Flood Fill tool and the Color Replacer tool?

The Flood Fill tool can fill pixels that match certain criteria (such as RGB value); in this way, it is similar to the Color Replacer tool.

The Flood Fill tool fills matching pixels that are contiguous to the initial pixel you click, whereas the Color Replacer tool changes pixels either within its brushstrokes or in the entire layer.

The Color Replacer tool changes the color of pixels based on RGB value. The Flood Fill tool changes pixels based on RGB, hue, brightness, or opacity values.

To limit changes to a specific area, make a selection in the image before you apply the Flood Fill tool. For information about selections, see Working with selections.

You can limit the flood fill to matching pixels of the current layer only by unmarking the Use all layers check box.
