I was shocked to see this web site on a Dell laptop at work and notice how all the colors were really hideous. I tried changing the color profile on the machine, but no dice.
The main offender was the background peach color. It really is a fairly subtle buff peach, but on the Dells it was shocking pink. Yuk!
Even the red was sort of a glowing ugly red instead of the nice all-American flag red that it's supposed to be.
If you're seeing some really awful colors, I apologize, and advise playing with the contrast and color profile to get a better view of the Internet.
