I have a photo as my desktop wallpaper-
but a dark blue/green color set as the main background in the advanced options settings.
that seems to make a blue box for the icon text to show in...
maybe that would work for you.
a few more ideas -
To make the Icon Text Black
to get black text under your icons is turn off the drop shadows on the text.
To do so go Control Panel --> System --> Advanced --> Performance Settings and there is a visual effect to turn on/off drop shadows. Turn it off. With Shadows the text is white, without shadows the text is black.
