Themer. You've seen them
First off, for the notification text, you have to redirect the colors of the systemui apk by adding a line in the com_android_systemui.xml I can't remember which color it is called, but if you've decompiled the system UI apk you can look at the XML files in systemui/layout most likely the status_bar.xml and it should call in the color in the XML. *breathes* now, did that make any sense?
