The status bar is an Android UI element that many seem to have minor (and sometimes major) issues with. It is one of the most commonly requested customizations out there, and can often be quite a fiddly and time consuming process. While there is certainly no shortage of ways to swap out things like battery and connectivity icons that cover multiple ROMs and devices, changing the color of the bar itself and elements such as the clock are not quite as readily available. Furthermore, doing so manually can be confusing for the average user.
XDA Forum Member WisdomSky made an attempt to address that issue with his eponymously titled Xposed Framework module. The module currently offers the ability to alter the color of the status bar itself and apply two different shades to the clock, these can also be applied as a gradient if you wish. In addition to altering the colors, you can replace the clock entirely with some custom text of your choice and adjust its font to your liking.
While these might only be simple changes, they are quite commonly requested by a lot of people. The flexibility of the Xposed Framework makes this a viable option for a wide range of devices. If you feel your status bar could do with a splash of color, be sure to check out the original thread.
