Computer Help.

It's a strange thing but I can't choose a different colour than White.
Perhaps going through the motions might reset the colour or you will be given a choice.

So.... Right click on the desktop
Choose "Properties"
In the Display Properties window choose the "Appearance" tab
Click on the "Advanced" button in the lower right corner of the tab
In the "Item" drop down box choose "Icon"

Now you will be offered a choice of Icon size, Font type and Font size.
On my machine the colour choices are faded out and not selectable.

See what you can do with that.
