" Maintainer: Neal Milstein - neal dot milstein at gmail dot com | |
" Last Change: 2011 Feb 1 | |
" | |
" This theme copies the colors from the TextMate theme Twilight. | |
" | |
" The theme is designed to be used on a black background. I only tested it | |
" using a 256-color terminal; I do not think it will work on much else (gvim, | |
" 8-color terminal, etc.). | |
" | |
" The functions in this theme that convert hex color codes to the nearest | |
" xterm-256 color number are from the theme desert2 (desert256), developed by Henry So, Jr. | |
" | |
" The colors of this theme are based on the TextMate Twilight theme | |
" – www.macromates.com | |
set background=dark | |
