I'm able to change a lot of colors through using the Android style documentation from here and looking at the source here and here.
Using what I learned above, I was able to change the ActionBar.TabBar, ActionBar.TabText, and ActionBar.TabView, but I don't know what that little highlight is called. Searching for a holo blue in the android source code from above also didn't help.
I still don't know if there is any way in styles.xml to specify that "blue" highlight color to be changed.
EDIT:
I know that I can use the the action bar style generator, but I'm looking at if I can set the color of it in code (whether it be java or xml). I would not like to have to generate a new drawable for this purpose.
