We learned a bit about the status bar in the last chapter when we discussed changing the session and window names. This status bar is highly customizable, and it's a great place to start learning about configuring tmux. We can change the status bar colors, what appears on the status bar, the alignment, and much more.
Let's add an item to our configuration to change the color of the status bar. As we saw by jumping in, the default color of the status bar is a shade of green. Note that there happens to be a shade of green in our configuration as well, but it is likely a different color on your terminal unless you are using the same color scheme as we are.
