Unless specified otherwise, all of the below tinting applies to both Lollipop and pre-Lollipop using AppCompat v21. To use the support version of these attributes, remove the android namespace.  For instance, "android:colorControlNormal" becomes "colorControlNormal".  These attributes will be propagated to their corresponding attributes within the android namespace for devices running Lollipop.  Any exceptions to this will be noted by including the "android:" prefix.

All Clickable Views:
-----------
* ripple effect (Lollipop only) -- "colorControlHighlight"

Status Bar:
------------
* background (Lollipop only) - "colorPrimaryDark"
