How to use true colors in vim under tmux?


1. Edit .tmux.conf

```tmux
# ！！！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

```vim
" 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
```
