If you're using a Windows based Operating System, you should be able to right click on your desktop and choose the properties option. From there, just pick the Appearance tab, and then the Advanced settings.
From there, you should be able to specifically customize the basic colour appearance of every item on the computer display. Including (I think) the background colours on most webpages. Of course, if your browser is set to allow local settings to ovver-ride yours, that won't help much, but it you wonk with the web page settings, you might lose pictures and the like from there too.
If you want to change the browser settings just to see what it might do for you, it's all reversible later. I just can't remember the specific paths to get to the browser settings off the top of my head. Poke about in the Internet Options, and I'm sure you'll find it there.
Hope this helps!
Oh.. gee.. I guess that tech support position actually helped me somehow. Wierd...
