Internet Explorer

In Internet Explorer --> Tools --> Options --> General Tab --> click on Colors button and uncheck "Use Windows Colors"... then you may select the colors you like for background and text.

You define your own stylesheet!
If you're unfamiliar with stylesheets these are used on the web to define every part of the graphical display of a web page. This means that no matter what the data on the page, a stylesheet can be applied by the author to define how it looks. This is also true of the local machine.
All you have to do is create a file in Notepad and call is MyStyle.css. Edit this in Notepad and add the line
BODY { background: white } interchanging 'white' with whatever colour you can devise. HEX colours are also permitted. These are #000000 to #FFFFFF representing black and white respectively. #FF0000 is red, #00FF00 is green, and #0000FF is blue. Its basically RGB triplets.
Now that you have your stylesheet, go to Internet Explorer tools, and select Accessibility. There should be a field where you can selet your own stylesheet file.
Browse 4 the file you created and Voila.
If all goes to plan IE should use your stylesheet before anything defined by the web author.

Hope this helps
