The text color of the names and descriptions is changed and the background color of the navigation bars is modified.
This is just an example that you could use for the Generic Photo Album (just publish a page with a title and
[wppa][/wppa] in the content only), you can do much more! You can modify most of the 'standard' settings in the Photo Albums -> Settings admin page that apply to the appearance of the display.
The title of the page is 'Custom page template'.
The contents of the page is: (besides the text above and below the black area):
[wppa type="slide" album="4"][/wppa]
