Color Schemes

Only Solarized scheme is supported. That too is on my list to investigate.

What color is out there?

To display all the colors, execute this in any vim edit session:

:so $VIMRUNTIME/syntax/colortest.vim

Turning it on

Method 1

First method to turn on syntax highlighting is at your console or in your vimscript (.vimrc) configuration file:

:syntax on

Method 2

" Syntax highlight
if &t_Co >= 256 
    if has("gui_running")
        colorscheme vividchalk
        set colorgui
    endif
    set tgc
endif
