I am forced to run this in my vim editor everytime I work.

highlight Normal ctermfg=grey ctermbg=black

What I want is for this to be automatic, I already have background set to dark but nothing is happening in vimrc. What should I do? Vimrc contents (first few lines)

syntax on

set background=dark

set ruler                     " show the line number on the bar

set more                      " use more prompt

set autoread                  " watch for file changes

set number                    " line numbers

Thanks.
