[Question] Android Nougat navbar

[devlerr]

I like the basic stock themes, but I'd like it to have the newer navigation bar. I'm talking about these two:

Either the former version: http://cdn.makeuseof.com/wp-content/uploads/2016/07/muo-android-layersnougat-azure.png

Or the newer Pixel version: http://www.droid-life.com/wp-content/uploads/2016/10/google-pixel-pixel-xl-black.jpg

How would I go about changing the theme to contain this navbar? Or can anyone make some of the Magazine theme to contain one of these navbars?

Those files are in the framework res somewhere... Just go find a theme that has these buttons changed and look up the exact directory.
