In the event that you want to add a little personal touch to your iOS 7 Notification Center, check out a new jailbreak tweak called NC Customizer by iOS developer Implosi0n.

With NC Customizer, you will have the ability to change the color and blur amount of Notification Center to your liking, as shown above.

The tweak adds a preferences pane to the Settings application where you can adjust the appearance settings to your liking.,
