I have been looking around for VIM color schemes and found some great ones out there (esp. by using http://code.google.com/p/vimcolorschemetest/), but I always want to change a
Launch vim, say ":help syntax", it has quick start etc.
For the complete templates look at your installation:
colorschemes are in /usr/share/vim/vimcurrent/colors/
languages syntax in /usr/share/vim/vimcurrent/syntax/
I didn't watch the "Creating colorschemes for Vim" episode of VIMcasts, but the others are really good.
colorschemes are actually vim scripts. You use the hi command for coloring, which works like
hi TextType guifg=#hexforegroundcolor guibg=#hexbgcolor gui=bold/italic/underlined/undercurled
(assumed you use gvim). If you type :hi
only, you get a complete list of text types with their current highlighting
see also http://vimdoc.sourceforge.net/htmldoc/syntax.html#:colorscheme
Vivify lets you interactively create vim colorschemes with color pickers and previews your scheme using several code samples.
May be you can find this colorscheme template useful: http://www.vim.org/scripts/script.php?script_id=106
The original description is
"The philosophy here is to provide a ready-to-uncomment list of highlight commands for all the important groups. Then you can deviate from the default until you come up with one you like."
