Restore original colors for WordArt, AutoShapes, and drawing objects
To restore a drawing object's original fills and borders, select the object, and then do one of the following:
Click the Undo button
On the Standard toolbar, click the Undo button
until the original fills and borders are restored.
This method works best when your most recent action was to change the object's borders or fill. Otherwise, you might undo other effects you've applied to the object.
Click the arrow next to the Fill button
On the Formatting toolbar, click the arrow next to the Fill Color
button ,
click
No Fill, and then reapply the object's original borders or fill.
