I have the following configuration in my .vimrc:

set background=dark

let g:gruvbox_bold = 1
let g:gruvbox_transparent_bg = 1
let g:gruvbox_improved_warnings = 1

colorscheme gruvbox

Yet the background of vim is a solid color. (My terminal bg is transparent)

I tried:

set background=dark
hi Normal ctermbg=None

let g:gruvbox_bold = 1
let g:gruvbox_transparent_bg = 1
let g:gruvbox_improved_warnings = 1

colorscheme gruvbox

To no avail.

The only solution I have is to override the colorscheme value by placing the ctermbg directive after the colorscheme load.

Am I doing something wrong ?
