I think the format has changed:

I have the same problem.

The individual -fg, -bg and -attr options have been removed; they were superseded by -style options in tmux 1.9.

I tried to update the theme here : #7

However, I don't understand what those attr "none" are doing, and when I tried to change it to style none, it doesn't work as expected.

Thank you @koalp for the PR. I will take a look at it and try to patch it soon.

Hey @koalp, you were interested in whatattr "none" is doing. Here you have a reference link from official man pages https://man.openbsd.org/tmux.1#STYLES

I've provided a fixup last night. Let know guys if the solution from #8 is working for you @AndreaOrru, @GenkunAbe, and @koalp.
