how to change vim background color in hex code or rgb color code?

Question

I am using vim 7.4.52 in Ubuntu 14.04 LTS.My vim background color is darkblue. I set this in .vimrc using set background darkblue

Now I want to set the background color with another color using hex code.

Is there any system to set this? i.e.set background=#300A24(this is my default terminal color)

Answer 1

To set the background (and foreground) to some explicit color, you probably want to use a highlight command in your vimrc, such as

" plain text
hi Normal     ctermfg=227 ctermbg=17

(assuming you are indeed in a terminal and not a gvim window).

The color codes '227' and '17' are interpreted in the terminal, and, sadly, they are not simple hex codes. To find which colors they correspond to in a given terminal, you can use this little script:

#!/usr/bin/bash   
for i in {0..255} ; do
  printf "\x1b[38;5;${i}mcolour${i} "
done
