I installed the Emacs Prelude as suggested in https://github.com/bbatsov/prelude . I find the background-color grey of the Zenburn theme to be disturbing. I wish to change the background-color to black. I tried (set-background-color "black") ,but it is not working. The background-color still remains grey. Can someone help on how to fix this ?
