tmux 2.1 background transparency I am using tmux 2.1 on Ubuntu 16.04. I would like to have the background have some transparency. A lot of times I need to reference something at the same time I use the terminal. I have looked at < and Reset background to transparent with tmux? this seemed to suggest that setting bg=default would do it but it gives me the default solid purple. I tried using a hex code of #80FFFFFF which tmux rejected. edit: The old post noted above does not explain how to set the transparency in tmux- at least not to me :( Help greatly appreciated.

The transparency preferences is not part from tmux, you need to change your `profile preferences` from your `terminal`

`Edit > Profile preferences > Colors`

uncheck `Use transparency from system theme` and

check `Use transparent background`

configure the level of opacity and that's it
