The ColorFlow Cydia tweak allows you to colorize your LockScreen and Music app. It will modify the design of the Music app and LockScreen based on the current artwork. It also includes an experimental option to remove white borders from album artwork (present in the iOS 7.1 firmware).
Note: Supports the iPhone 5s (arm64), and it’s not compatible with BlurredMusicApp. Configure ColorFlow from the Settings app.
ColorFlow is $1.99 on the Cydia Store for iPhone in the default BigBoss repository. Don’t forget to let us know what you think about this tweak in the comments below.
