I get asked this a lot, and some people accidentally push the button, "hide user customization" located on the top right hand side of someone page. This is written in the same place where on your own page it would say "customize profile." When you go to someone page does it say, "hide user customization"? If it says, "show user customization", click this, and you will see colors again.
The only other thing I can think of, is that you have changed your actual computer settings. |
