The layer color you see may be different from what you see in the figure, and that’s okay.

Duplicating layer content
You can also use the Layers panel as another method for duplicating layers and other content.
Next, you’ll duplicate the Front sublayer, then move the content onto the right-hand artboard,
and finally duplicate content between layers.
Drag the Front sublayer down to the Create New Layer button ( ) to make a copy of the layer.
Double-click the new layer name (Front copy) and name it Back.
The <Compound Path> object at the top of the Phone Body layer also needs to be in the Front
sublayer and the Back sublayer. Next, you’ll drag a copy into the Back sublayer and then drag
the original into the Front sublayer.
