Paint with the Brush tool

Use the Brush tool to paint on a layer in the Layer panel with the current foreground color.

Important: To specify settings for a paint stroke before you apply it, use the Paint and Brush Tips panels. To change and animate properties for a paint stroke after you’ve applied it, use the stroke’s properties in the Timeline panel.

Select a color for the Brush tool

Do any of the following with the Brush tool active:

  • To select a foreground color with the Color Picker, click the Set Foreground Color button in the Paint panel.
  • To select a foreground color from anywhere on the screen with the eyedropper, select the eyedropper in the Paint panel and then click to sample the color under the pointer. Ctrl-click (Windows) or Command-click (Mac OS) to sample the average color of a square three pixels on a side.
    You can quickly activate the eyedropper for use within the Layer panel by pressing Alt (Windows) or Option (Mac OS) when the pointer is in the Layer panel.
  • To switch the foreground color with the background color, press X or click the Switch Foreground And Background Colors button .
  • To reset the foreground color and background color to black and white, press D.
Note: To change or animate the color of a brush stroke after painting, use the Color property in the Stroke Options group in the Timeline panel.

Paint on individual frames with the Brush tool

You can paint on individual frames over a series of frames to create an animation or to obscure unwanted details in your footage. Rotoscoping is a special case of painting or drawing on individual frames in which some item in the frame is being traced.
If your output will be interlaced, double the frame rate of your composition before painting on individual frames. (See Change frame rate.)
