This is a colorscheme for the EFL-based terminal, "terminology." It uses colors similar to the gvim "desert" theme.
Get a git checkout of 'terminology'. Check out the tag matching your installed version (they change how ~/.config colorschemes work between 1.11 and master). Find the 'add_color_scheme.sh' line at the end of COLORSCHEMES.md and use that with this Desert.ini file.
