As the title says, I want to know how can I enable the guifg and guibg in vim colorschemes. I already wrote in my vimrc set t_Co=256, but it enables only ctermfg and ctermbg for 256 colors.
I have Debian 7.0 wheezy and I'm using gnome-terminal (but I tried with terminator terminal and also doesn't work)
Thanks in advance.
The highlight attributes starting with gui..= are only ever used in GVIM, not in terminal Vim; in the GUI, 24-bit colors are available, but most terminals stop at supporting 256 different colors.
Plugins like CSApprox can take the GUI color definitions and convert them to a closely matching 256-color cterm color palette for high-color terminals. This helps with colorschemes that otherwise only pick from the bland default 16-color terminal color palette, or only provide GUI color definitions.
