tmux 如何自定义背景颜色 | How does the tmux color palette work?

坑1：256 color support for vim background in tmux

解决终端颜色配置与 tmux 颜色配置不匹配问题。

https://superuser.com/questions/399296/256-color-support-for-vim-background-in-tmux

原因

From the look of your .bashrc and .profile, the shells inside tmux are overriding the ‘default-terminal’ setting in your tmux conf. Something like this:

• tmux creates new shell with TERM=screen-256color
• .bashrc/.profile run, set TERM=xterm-256color
• vim runs, tries to use incorrect TERM for tmux

you can check this by running

echo $TERM

in a fresh tmux shell.

Tmux is relatively picky about having a terminal set correctly. If you can, set the term value in gnome-terminal’s configuration, not in your .bashrc. Failing that, surround those settings with a check for “screen” or “screen-256color” TERM, and don’t reset them in that case.

Tmux REALLY wants the terminal set to screen or screen-256color

解决方法

This is what worked for me in #Ubuntu and #Mac:

# File: ~/.bashrc (Ubuntu), ~/.bash_profile (Mac)
# for VIM and TMUC
if [ "$TERM" = "xterm" ]; then
  export TERM=xterm-256color
fi
alias tmux='tmux -2'  # for 256color
alias tmux='tmux -u'  # to get rid of unicode rendering problem

Reload settings:

$ source ~/.bashrc # Ubuntu $ source ~/.bash_profile # Mac

Set up .bashrc for Mac (as it is used by tmux)

# File: ~/.bashrc (Mac)
source ~/.bash_profile

Set up “default-terminal” option in ~/.tmux.conf.

# File: ~/.tmux.conf
set -g default-terminal "screen-256color"  # Mac and Ubuntu

坑 2：Change background color of active or inactive pane in Tmux

详解 .tmux.conf 配置文件设置背景颜色的方法。其中，fg 是字体颜色，bg 是背景颜色。

It seems that tmux-2.1 (released 18 October 2015) now allows the colours of individual panes to be specified. From the changelog:

* 'select-pane' now understands '-P' to set window/pane background colours.

e.g. [from the manual] to change pane 1’s foreground (text) to blue and background to red use:

select-pane -t:.1 -P 'fg=blue,bg=red'

To mimic iTerm colour scheme:

To answer the original question, I use the following lines in my ~/.tmux.conf for setting the background/foreground colours to mimic the behaviour in iTerm:

#set inactive/active window styles
set -g window-style 'fg=colour247,bg=colour236'
set -g window-active-style 'fg=colour250,bg=black'

# set the pane border colors 
set -g pane-border-style 'fg=colour235,bg=colour238' 
set -g pane-active-border-style 'fg=colour51,bg=colour236'

坑 3：Reloading tmux config

写完配置文件后，需要手动 source 使其生效。

If you have made changes to your tmux configuration file in the ~/.tmux.conf file, it shouldn’t be necessary to start the server up again from scratch with kill-server. Instead, you can prompt the current tmux session to reload the configuration with the source-file command.

This can be done either from within tmux, by pressing Ctrl+B and then : to bring up a command prompt, and typing:

:source-file ~/.tmux.conf

Or simply from a shell:

$ tmux source-file ~/.tmux.conf

This should apply your changes to the running tmux server without affecting the sessions or windows within them.

You can create it with for i in {0..255}; do printf "\x1b[38;5;
