According to https://github.com/psmux/psmux/blob/master/docs/configuration.md, the default background of status bar was set to green.
I want to override it with the background color of the terminal emulator.
For example with set -g status-style fg=white,bg=default.
However, it doesn't work. the background is still green.
Specifying a color e.g. black work btw.
