mrkn256 is a colorscheme for vim designed by mrkn. It is avaiable on 88- and 256-color xterm, and on gvim.
This is a colorscheme designed by mrkn based on "desert256" colorscheme created by Henry So, Jr. This colorscheme is designed to work with with 88- and 256-color xterms.

The ancestor version "desert256" colorscheme is available at http://www.vim.org/scripts/script.php?script_id=1243
The real feature of this colorscheme, with a wink to the "inkpot" theme, is the programmatic approximation of the gui colors to the palettes of 88- and 256- color xterms. The functions that do this (folded away, for readability) are calibrated to the colors used for Thomas E. Dickey's xterm (version 200), which is available at http://dickey.his.com/xterm/xterm.html.
Henry had struggled with trying to parse the rgb.txt file to avoid the necessity of converting color names to #rrggbb form, but decided it was just not worth the effort. I thank a lot for his results.
Copy this file into ~/.vim/colors (or $VIM/vimfiles/colors in Windows). Start it from within vim using :colorscheme mrkn256.
