- Do one of the following:
- In the Onion Skin toolbar, click the Onion Skin button.

By default, the Onion Skin for the previous panel will display in the Stage and Camera view in red, and the Onion Skin for the next panel will display in green.
TIP By default, previous drawings appear in red and next drawings appear in green. You can also change the colours in which the previous and next drawings display in the Colours tab of the Preferences dialog. You can also configure the Onion Skin to display the actual colours of the drawings, or just their outlines, in the Camera tab of the Preferences dialog
—see Camera Preferences and Colours Preferences.
