" Theme to mimic the default colorscheme of powerline
" Not 100% the same so it's powerline... ish.
"
" Differences from default powerline:
" * Paste indicator isn't colored different
" * Far right hand section matches the color of the mode indicator
"
" Differences from other airline themes:
" * No color differences when you're in a modified buffer
" * Visual mode only changes the mode section. Otherwise
"   it appears the same as normal mode
