Powerline works perfectly in gvim, but any terminal emulator omits the color highlight, including konsole.

I had the same problem, the solution for me is to use "xterm-256" as the reported terminal type. (I'm using iterm2).
Turned out I needed CSApprox, available as a vim script or an AUR package.
