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.
