@sorin88:
There is always at least two viewpoints to a development thread. One is to discuss issues arising while actually developing, the other is to discuss enhancement and future road map to have something to develop. Discussing usabilty would meet requirements of a development thread and one issue of usabilty is colour schemes.
The colour is not only good looks. It is user experience by integrating with the OS. It is as well battery life by choosing black background on a display which actually benefits from black.
