How to use true colors in vim under tmux?

[rinetd]

1. Edit .tmux.conf

# ！！！importent！！！ 开启24 bit color 其他方式都无效
set -g default-terminal "tmux-256color"
set -ga terminal-overrides ",*256col*:Tc"

2. Edit: .vimrc

" Enable true color 启用终端24位色
if exists('+termguicolors')
  let &t_8f = "\<Esc>[38;2;%lu;%lu;%lum"
  let &t_8b = "\<Esc>[48;2;%lu;%lu;%lum"
  set termguicolors
endif

For me, it was screen-256color. My tmux complains it can't recognize tmux-256color. Other than that, it's all good. Thanks!

for anyone tried this trick but still not working, noted that tmux 2.6 or higher is required.

Thank you!
For me on ubuntu 19.04, tmux 2.8 and nvim v0.4.0-dev it was:

.tmux.conf:
set -g default-terminal "xterm-256color"
set -ga terminal-overrides ",*256col*:Tc"

.vimrc:
if (has("termguicolors"))
  set termguicolors
endif
