ClockColors is a tweak released last night in Cydia, and it is made especially for those who want to customize their iDevice's Lockscreen a little. The tweak has a settings menu in the Settings app iOS, and there it allows users to change the color of the clock displayed in the Lockscreen of their own terminals. In the image above you have shown how the watch will look as soon as you change its color, and that settings menu is intuitive and you will immediately realize how everything must be changed to change the color.
ClockColors is available for free in Cydia.
