When I am in plain fish shell, a command is highlighted like so:

enter image description here

but when I am in byobu-screen and type the same thing, I get:

enter image description here

When I do a fish_config and look at my color palette, nothing is set to that darker blue color.

Note: I am on Mac OS X 10.9.1, and Byobu version 5.69 installed via Homebrew.

Okay, switching to byobu-tmux seems to solve the problem. – David Sawyer Feb 1 '14 at 20:55

I think that's because screen by default on OSX is only 8 colors, while fish wants to use 256 (it's actually not related to byobu, which is why it works when you switch to tmux).

To get it to work, you'd need to recompile screen with 256 color support. You could do something like this:

git clone git://

cd screen/src


./configure --enable-colors256


sudo make install

cp screen /usr/local/bin/ # this should have precedence over the default screen in yr path

congrats on the engagement ;)

Beautiful. Thank you my friend! – David Sawyer Mar 1 '14 at 22:40

Byobu now defaults to tmux (or at least, it does on Ubuntu). Append this to ~/.byobu/profile.tmux:

set -g default-terminal "screen-256color"
