The Spray brush imitates spraying paint on an image. It does not apply paint in a continuous layer but rather as droplets scattered along the stroke.

You can change the paint color using the Color panel, Swatches panel, Color Wheel panel, or by clicking the image with the Eyedropper tool. To pick a color sample, press and hold the I key and then click the image with the Eyedropper tool. After the hotkey is released, the painting tool becomes active again.


The basic tool settings are shown in the Tool Options panel above the Image Window or by right-clicking on the image. To display the full list of parameters, press the tool icon in the Tool Options panel or use the F5 key. To specify the parameter settings, enter a numerical value in the parameter’s field or use the slider.

The parameters in the Dynamics tab affect the dynamic changes when applying paint drops.

In addition to the above-mentioned parameters, you can adjust the advanced settings.


Press the Default button to set all settings to their default values.

To spray paint along a straight line, click to set the starting point, then hold down Shift, move the cursor, click the end point, and release Shift. If Shift is not released, the line will be drawn following all selected points.
