Incorrect background color in neovim in tmux

Problems summary

When using neovim in tmux the background color renders in an incorrect brown/gray shade. The color scheme works as expected in neovim outside of tmux.

Environment Information

  • terminal: iTerm2 3.1
  • nvim version: 0.1.7
  • tmux version: 2.3

I am using the recommended iterm2 terminal color scheme which has been added in the iTerm preferences. I am not sure if this is a result of the theme or tmux. However, I have previously used solarized which has worked fine under the current configurations. I am also using zsh and oh-my-zsh if that matters at all.

Minimal conf files

.vimrc:

call plug#begin('$HOME/.config/nvim/plugged')
...
Plug 'mhartington/oceanic-next'
...
call plug#end()

" For Neovim 0.1.3 and 0.1.4
let $NVIM_TUI_ENABLE_TRUE_COLOR=1

" Or if you have Neovim >= 0.1.5
if (has("termguicolors"))
 set termguicolors
endif

syntax enable
colorscheme OceanicNext

.tmux.conf:

...
set -g default-terminal "screen-256color"

To reproduce

Open nvim in tmux.

This was an issue with truecolor in tmux. It was fixed with

tmux attach
tmux set-option -ga terminal-overrides ",xterm-256color:Tc"
tmux detach
tmux attach

in the terminal. Just in case anyone else encounters this!

It doesn't work in my case.

This is how i made it work, add this in .tmux.conf

set -g default-terminal "screen-256color"
set -ga terminal-overrides ",*256col*:Tc"
