Opera icon is red on all my installations. If it works, don't worry about it.

Red icons in the task bar can also indicate that the program is trying to display something.

It means that there was a failed download in Opera. When you start to download, the Opera icon will have a green progress bar across the icon. If the download completes the icon returns to normal, if a download fails it turn Red. How to Resume ANY Failed Download in Opera Mini !! Enjoy | BCA Rocks

LOL. Originally looked at the icon on a computer with poor graphics. On a good unit now and I see the problem.
