WezTerm Window Tint

Project-aware window tinting for WezTerm.

WezTerm Window Tint colors your terminal window based on the project in the active tab or pane. Open several terminals across several repositories and the active project gets an immediate, subtle visual identity.

It is a WezTerm Lua plugin. Require it from wezterm.lua, configure the options you want, and reload.

Features

• Project colors based on the active pane's git root.
• Automatic fallback to cwd for non-git folders.
• Runtime-scoped colors from a curated 12-color palette.
• Collision avoidance for the first 12 distinct projects.
• Retinting when you switch tabs or panes.
• Live cd retinting when WezTerm receives cwd updates.
• Subtle frame, tab bar, active tab, and optional status badge tinting.

Colors intentionally reshuffle after restarting WezTerm. The goal is quick session identity, not permanent project branding.

Install

Add this to ~/.config/wezterm/wezterm.lua:

local wezterm = require 'wezterm'
local config = wezterm.config_builder()

local window_tint = wezterm.plugin.require('https://github.com/willytop8/Wezterm-Window-Tint')

window_tint.apply_to_config(config, {
  show_badge = true,
  set_retro_tab_bar = true,
})

return config

If you already have a wezterm.lua, keep your existing config and add only the wezterm.plugin.require(...) and window_tint.apply_to_config(config, ...) lines before return config.

Reload WezTerm with Cmd+Shift+R on macOS, or quit and reopen it.

To update later:

wezterm.plugin.update_all()

Remove that line after WezTerm has updated the plugin.

Manual Install

If you prefer not to use WezTerm's plugin loader, copy the module into your config directory:

mkdir -p ~/.config/wezterm
cp wezterm-window-tint.lua ~/.config/wezterm/wezterm-window-tint.lua

Then require it from wezterm.lua:

require('wezterm-window-tint').apply_to_config(config, {
  show_badge = true,
  set_retro_tab_bar = true,
})

Options

window_tint.apply_to_config(config, {
  show_badge = true,
  set_retro_tab_bar = true,
  retint_interval_seconds = 1,
  palette = {
    { name = 'rose', hex = '#fb7185' },
    { name = 'orange', hex = '#fb923c' },
    { name = 'amber', hex = '#fbbf24' },
  },
})

• show_badge: show a left status badge with the color name and project path.
• set_retro_tab_bar: set use_fancy_tab_bar = false for reliable tab tinting.
• retint_interval_seconds: status update interval used to refresh the active pane's cwd.
• palette: optional list of { name, hex } entries.

Live cd Retinting

WezTerm can track cwd through shell integration and OSC 7. If changing directories does not retint the window, add this to ~/.zshrc:

_osc7_cwd() {
  printf '\e]7;file://%s%s\e\\' "${HOST:-localhost}" "$PWD"
}
autoload -Uz add-zsh-hook
add-zsh-hook chpwd _osc7_cwd
add-zsh-hook precmd _osc7_cwd

Then restart your shell.

Notes

Colors are assigned for the current WezTerm runtime and reshuffle after restart. If your config already customizes tab titles, window frames, or tab bar colors, merge those settings with this module's handlers and overrides.
