Hoping someone can point me in the right direction on this.

Hoping someone can point me in the right direction on this. I'm busy evaluating Delphi XE4 (trail) and am trying to build an IOS application. My issue is that the FMX does not allow you to change background colours of things like Panels and buttons etc. I have done some searching and they all point to right clicking on the object and editing the styles, however in the version I have (trail) those menu items are not there. Is there any other way of doing this? Or if someone could point me to a site or something that would help me understand this.
