Trying to change borders in Borders theme

Hi I've managed to convert most things, but I stuck on the following:

--- The thickness of all the borders in the borders theme except the photo or thumbnail borders.

--- The colour of the background under the following:

Albums heading on left
Newest Pictures heading
Main Menu Previous/Next

These are all currently white. I reckon I've changed #FFFFFF to another colour in every file, but it has no affect on the above.

Any help will be appreciated
