How to set a custom color to folded highlighting in .vimrc (for use with putty)
The cterm
in ctermbg
is short for "color terminal". It is used to define the background color when Vim runs in a terminal emulator and can only accept named colors like grey
or cyan
or color numbers like 7
. Hexadecimal values only work in GVim/MacVim and must be used with guibg
/guifg
like that:
hi Folded guibg=#A0A0A0
In your shell, do $ echo $TERM
: it should return something like xterm
, screen
, xterm-256color
or some variants.
If you run Vim in a terminal emulator that can't display more than 8/16 colors ($TERM
doesn't contain 256color
), you won't be able to use a different shade of grey unless you define your own palette in your terminal emulator.
It should look like this:
hi Folded ctermbg=7
or like that:
hi Folded ctermbg=grey
If your terminal emulator advertises itself as "256 colors ready" ($TERM
contains 256color
), you are able to use any color in this chart as long as you use its number (242
) and not its hexadecimal value.
It should look like this:
hi Folded ctermbg=242

Adding the following to
.vimrc
works:hi Folded ctermbg=Grey
but it's still too bright and prominent, so we want to specify a more specific color triplet instead, like so:
:hi Folded ctermbg=#A0A0A0
but vi won't accept it:
Error detected while processing /home/guest/.vimrc: line 10: E421: Color name or number not recognized: ctermbg=#A0A0A0
Any suggestions?
