Good news everyone! Starting Lollipop (21) you can use attributes to reference stuff like colors e.g. ?attr/colorPrimary.

Original answer:

As far I know you cannot reference style attributes from drawables, I couldn't find an usage like that in Android platform resources ($ANDROID_HOME/platforms/android-*/data/res/), all I see is that every drawable even for gradient drawables are defined in place or they just reference other drawables like color drawables.

Here is a related bug report for this (star it):

You can workaround this by using separate xml drawables like explained at:
