To celebrate the 14.10 code name 'Utopic Unicorn' and to demonstrate the easy customisability of Xubuntu, highlight colors have been turned pink for this release. You can easily revert this change by using the theme configuration application under the Settings Manager; simply turn Custom Highlight Colors 'Off' and click 'Apply'. Of course, if you wish, you can change the highlight color to something you like better than the default blue. Starting with Xubuntu 14.10, you should use pkexec instead of gksudo for running graphical applications with root access from the terminal for improved security.

About Xubuntu

Xubuntu is a Linux distribution based on Ubuntu. Unlike its parent, however, Xubuntu uses the light-weight Xfce desktop environment and is optimised for lower-end machines. The distribution includes only GTK+ applications where possible.
