My ITunes Turned Pink

For about the past 2 months my ITunes screen has turned pink, I have no clue what happened, one second it was normal and the next it was pink and has yet to change back. I have uninstalled and reinstalled ITunes a number of times, I've ran antivirus's and still nothing. Everything else on ITunes works fine and normal, im just kind of curious why it did that and how I can get it to change back to normal
