Android Color?

Is there a standard color set for the android platform?  I would like to have a version of the TIWIphoneStyle with the colors set to android defaults and conditionally use it based upon the platform the app is running on. 

1. Is that possible?
2. Is there a standard color set for android?  The gradients values are where I get lost.  I could experiment to produce my own, but having it as part of your component set would be nice?
3. Are there any plans to support such a feature?

That's currently not available but it is being considered to add this in a future update.
