The instructions would be more clear if stated as - **background transparency/opacity of the icon**.

The background transparency of different gifs can be checked by setting the background of the Frame to a different color.  For instance `setBackground(Color.YELLOW)` here and in the original test.

Adding a different background color instead of white makes it easier for the tester to compare the different types of icon.
