I’ve been using kitty and tmux together for years and recently realized my setup for true colors was broken, thanks to neovim’s :checkhealth command. After some searching and trial and error, the setup I ended up at was this: Remove any export TERM lines from .zshrc, .bashrc, etc. Set these options in tmux: set -g default-terminal "screen-256color" set-option -sa terminal-overrides ",xterm-kitty:RGB" Kill tmux, close kitty, reopen and true color support should be enabled
