Powerline has No Highlight/Color

Question

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

Answer 1

Turned out I needed CSApprox, available as a vim script or an AUR package.

Answer 2

For me I had to add

set t_Co=256

to ~/.vimrc.

Answer 3

I had the same problem, the solution for me is to use "xterm-256" as the reported terminal type. (I'm using iterm2).
