Vim 7.3 is distributed with file vim73/syntax/syncolor.vim. The following is an example of how that file might be changed. These comments were originally posted at Changing the default syntax highlighting, and the comments were then moved to Highlighting, and then moved to here.
I want a simple syntax highlighting which does not take attention from the real thing. Color codes are:
- Green for comments
- Blue for keywords/types
- Bluebold for flow-control
- Brown or gray for strings and constants
- Black (or navy) for the rest
For that purpose I changed the "syncolor.vim" file (and it works best for light background xterm).
Some changes are:
SynColor Comment term=bold cterm=NONE ctermfg=DarkGreen ctermbg=NONE gui=NONE guifg=MediumSeaGreen guibg=NONE SynColor Constant term=underline cterm=NONE ctermfg=DarkRed ctermbg=NONE gui=NONE guifg=SlateGrey guibg=NONE SynColor Special term=bold cterm=NONE ctermfg=DarkRed ctermbg=NONE gui=NONE guifg=DarkRed guibg=NONE SynColor Identifier term=underline cterm=NONE ctermfg=DarkCyan ctermbg=NONE gui=NONE guifg=DarkCyan guibg=NONE SynColor Statement term=bold cterm=NONE ctermfg=Blue ctermbg=NONE gui=bold guifg=SlateBlue guibg=NONE SynColor PreProc term=underline cterm=NONE ctermfg=DarkBlue ctermbg=NONE gui=NONE guifg=SlateBlue guibg=NONE SynColor Type term=underline cterm=NONE ctermfg=DarkBlue ctermbg=NONE gui=bold guifg=Blue guibg=NONE SynColor Underlined term=underline cterm=underline ctermfg=DarkMagenta gui=underline guifg=SlateBlue SynColor Ignore term=NONE cterm=NONE ctermfg=white ctermbg=NONE gui=NONE guifg=bg guibg=NONE
The changed syncolor.vim file follows.

" This file sets up the default methods for highlighting.
" It is loaded from "synload.vim" and from Vim for ":syntax reset".
" Also used from init_highlight().

" ":syntax enable" keeps any existing colors
command -nargs=* SynColor hi def <args>

elseif syntax_cmd == "reset"
" ":syntax reset" resets all colors to the default

" User defined syncolor file has already set the colors.
finish

" Many terminals can only use six different colors (plus black and white).
" Therefore the number of colors used is kept low. It doesn't look nice with
" too many colors anyway.
" Careful with "cterm=bold", it changes the color to bright for some terminals.
" There are two sets of defaults: for a dark and a light background.
