Colours are not applied when inside tmux

[Ch00k]

I invoke fzf with Ctrl-R (Bash history). Te colours work OK when run in plain Bash, but don't work when inside tmux.

My .fzf.bash:

# Setup fzf
# ---------
if [[ ! "$PATH" == */usr/local/opt/fzf/bin* ]]; then
  export PATH="$PATH:/usr/local/opt/fzf/bin"
fi

# Auto-completion
# ---------------
[[ $- == *i* ]] && source "/usr/local/opt/fzf/shell/completion.bash" 2> /dev/null

# Key bindings
# ------------
source "/usr/local/opt/fzf/shell/key-bindings.bash"

# Base16 Flat

hi,

I could reproduce your issue. I think it has to do with tmux settings'. For exemple, I'm using termite and I needed to add the following line in my tmux.conf to enable true colors: set -ga terminal-overrides ",xterm-termite:Tc". But it might be different depending on the terminal emulator you are using.

Adding set -ga terminal-overrides ",xterm-256color:Tc" to .tmux.conf worked. Relevant issue for the terminal emulator I use: https://github.com/jwilm/alacritty/issues/109
