Pop!_OS 24.04 on COSMIC in Harbor Dark gold: desktop, terminal, shell, Firefox, Brave, cursor. The dark half of a pair; the light sibling is cosmic-whitegold-theme.
Inspired by omarchy-harbordark-theme.
Firefox uses the cosmic-darkgold-theme add-on. Icons: Cosmic-DarkGold, Kanagawa recolored to this palette. Cursor: Oxygen recoloured to the icon colours (Gold, Red, Dark), COSMIC-fixed.

Settings → Desktop → Appearance → Dark → Import → cosmic/DarkGold.ron
Accent is gold #C0AF7F. Use the + control if you want a custom swatch.
Frosted glass is on in the .ron at frosted: VeryLow for windows, panel,
applets and system UI (maximized apps stay solid). Adjust it on Appearance →
Style → Frosted glass after import; those sliders survive a theme switch.
Export from Appearance if you tweak backgrounds / tints so you do not lose them.
Known COSMIC bug: moving the frosted glass opacity / thickness sliders can
reset text_tint to #FFFFFF. If your text turns white, re-import
cosmic/DarkGold-fixed-text.ron (tint pinned to gold #C0AF7F), or
cosmic/DarkGold-Light-fixed-text.ron in light mode, where white text on
parchment is unreadable (dark gold #655628). Upstream fix proposed in
libcosmic#1450, not merged.
cosmic/config/ holds the settings that make up the look and rarely change
(panel, dock, applets and shortcuts are left out on purpose):
| Where | Setting |
|---|---|
| Fonts | Interface Maple Mono Normal, monospace Maple Mono Normal NFM |
| Icons | Cosmic-DarkGold-Gold |
| Windows | Minimize / maximize buttons hidden, theme applied to GNOME apps |
| Terminal | Maple Mono 15 (weights 500 / bold 800 / dim 300), 77% opacity, no header bar, Harbor Dark / Harbor Light |
Install the Maple fonts (Maple Mono Normal and Maple Mono Normal NFM) and the Cosmic-DarkGold icons (see Icons below) and import the terminal schemes first, then:
./cosmic/install.shIt backs up each file it replaces to *.bak and COSMIC applies it live.
The desktop .ron does not colour ANSI text.
- COSMIC Terminal → View → Color schemes… (not Settings → Appearance)
- Dark tab → Import →
cosmic-term/DarkGold-term.ron - View → Settings → Appearance → Color scheme (dark) → Harbor Dark
If a profile is set as default, set the scheme on that profile too or the dropdown will look like it did nothing.
There are variants for both modes with gold or slate text (to pair with the
gold text tint, or match btop). Previews and which to pick:
cosmic-term/README.md.
Nala progress boxes use Rich green. In this scheme that slot is gold #C0AF7F.
COSMIC keeps a separate theme for Dark and Light, so the light look needs its own import. Import both once and the Dark / Light toggle (or auto-switch) flips between them.
Desktop: Settings → Desktop → Appearance → Light → Import →
cosmic/DarkGold-Light.ron
Terminal: View → Color schemes… → Light tab → Import →
cosmic-term/DarkGold-Light-term.ron, then View → Settings → Appearance →
Color scheme (light) → Harbor Light (gold and slate variants in
cosmic-term/README.md).
Same palette, flipped: a darker parchment window background with lighter cards on top so panels stand out, charcoal text, and deeper shades of the accents so they stay readable (all at least 4.5:1 contrast on the window background).

Spacing, corners, gaps and frosted glass match the dark theme.
For a full light rice (parchment palette, own wallpapers, terminal, btop, nvim), see cosmic-whitegold-theme.
The cosmic-darkgold-theme Firefox add-on and firefox/chrome/ are dark only.
For a light Firefox, use White Gold's
cosmic-whitegold-theme.
Not covered yet: update_system.sh uses light text colours that are hard to
read on a light terminal.
Two layers:
- Theme (colours): install cosmic-darkgold-theme on addons.mozilla.org (formerly harbordark). This is the main look.
- Stylesheets (optional):
firefox/chrome/adds rounded corners, gold menu hover, gold accents and blank new-tab tiles on top of the add-on (they also work with Firefox's built-in Dark theme):
chmod +x firefox/install.sh
./firefox/install.shFully quit Firefox afterward. Details: firefox/README.md.
brave/theme is a Chromium theme with the Firefox theme's colours: near-black
frame, charcoal toolbar, gold icons and inactive tabs, coral on the active tab.
Brave, Chrome, Chromium and Edge take it, and it loads straight from the
clone, so no Chrome Web Store or Google account is needed:
brave://extensions → Developer mode → Load unpacked → brave/theme
Leave the clone in place, Brave keeps reading the folder. Colours, limits and
packing a .crx: brave/README.md.
For the unofficial claude-desktop-extra
Linux build. claude-desktop/cosmic-darkgold.jsonc is one theme with both halves:
DarkGold in dark mode and White Gold in light mode, so Claude's own
Settings → Appearance toggle switches between the two rices.
Colours come from cosmic/*.ron, contrast-checked (text and button text
4.5:1, accents 3:1).
./claude-desktop/install.shIt copies the file into ~/.config/Claude/themes.d/. Then press
Ctrl+Shift+T in Claude Desktop and pick cosmic-darkgold.
The same file ships in cosmic-whitegold-theme,
so installing from either repo gives the same theme.
vscode/ is a colour theme extension for Cursor with
both halves of the pair: Cosmic DarkGold and Cosmic White Gold. It is a plain
VS Code theme extension, so VS Code and VSCodium take it too, and the same
folder ships in cosmic-whitegold-theme. Code is coloured the way Neovim is in
each rice; the workbench takes the desktop's window and container colours,
with the accent on the active tab, buttons and menu highlight, and the
integrated terminal uses the COSMIC Terminal scheme. Cursor builds its Agent
and chat panels from the same theme colours, so they follow along.
./vscode/install.shIt packs vscode/ into a .vsix and installs it with
cursor --install-extension; run it again after editing the theme. Then press
Ctrl+K Ctrl+T in Cursor and pick
Cosmic DarkGold. Three lines in Cursor's settings.json make it follow
COSMIC's Dark / Light toggle between DarkGold and White Gold; they, the colours and
the contrast notes are in vscode/README.md.
telegram/cosmic-darkgold.tdesktop-theme is a Telegram Desktop theme: steel
text (the Harbor Dark Steel shade, lifted to #A3AAAD for 4.5:1 on hover and
bubble colours) on a charcoal chat list and background, dark-grey incoming and
warm-brown outgoing bubbles, gold for the accent, links, unread badges and
buttons (with charcoal text on them), brass for online status and read ticks.
Group member names use the rice's terminal colours. Text and badge colours are
contrast-checked at 4.5:1 or better, except disabled menu items.
Settings → Chat Settings → Chat wallpaper → Choose from file →
telegram/cosmic-darkgold.tdesktop-theme → Apply this theme.
The colours live in telegram/colors.tdesktop-theme, which is plain text;
build.sh zips it with the chat background into the .tdesktop-theme. The
background is the plain window colour; to put a wallpaper behind the chat instead
(ImageMagick re-encodes it to a 2560px JPEG, Telegram caps theme files at 5 MB):
./telegram/build.sh --wallpaper backgrounds/darkgold-anime.pngBuilt against Telegram Desktop 7.3.1. Calls, group calls, statistics charts and premium badges keep Telegram's own colours.
Telegram has no dark / light pairing, so White Gold, the light half, ships its own theme.
Wallpapers ship in backgrounds/, named darkgold-<subject>.png.
Four are the Harbor Dark originals from
omarchy-harbordark-theme
(MIT), unchanged, since Harbor Dark is this palette: the reaper (the one in the
screenshot), the Hyundai blueprint, the harbor in space and the space monolith. The
rest are renders in gold and coral on charcoal: the geisha, The Greek eagle, and three
new scenes, city, panel and tower.
Settings → Desktop → Wallpaper → Add image → pick a file from backgrounds/.
Cosmic-DarkGold, the Kanagawa icons
by Fausto Korpsvart recolored to this palette in
cosmic-icon-themes. Folders come in
three colors: Gold #C0AF7F (default), Red #E75A50 and Dark #2A2A29 with gold symbols.
./icons/install.sh # Gold folders
./icons/install.sh --variant Red # or DarkIt downloads the pack from the latest cosmic-icon-themes release, checks its SHA256,
installs it to ~/.local/share/icons/ and sets it as the COSMIC icon theme.
Restart open apps afterwards (Files caches icons per window).
Add --system to install to /usr/share/icons instead, for every user and the
login screen (asks for sudo); --user is the default.
Oxygen cursors recoloured to the icon colours, one per folder colour of the Cosmic-DarkGold icon pack: Gold (default), Red, Dark. Patched with the cursor names COSMIC apps ask for. COSMIC has no cursor picker yet, so the script sets it:
./cursors/install.sh # Gold
./cursors/install.sh --variant Red # or another, see --list
rebootPreviews, what the script touches, how to undo it and how the colours are made:
cursors/README.md.
Both need a Nerd Font in the terminal for the icons (the screenshot uses Maple Mono NFM).
fastfetch/ holds a Harbor Dark config with a COSMIC logo in coral and
Hardware / Software / Age boxes. install.sh backs up any existing
~/.config/fastfetch/config.jsonc to config.jsonc.bak before copying.
./fastfetch/install.sh
fastfetchzsh/darkgold.zsh is the rice part of the shell only: LS_COLORS (also used
by lsd for file names and by the completion menu), DarkGold colours for
zsh-autosuggestions and zsh-syntax-highlighting, the lsd / bat / nvim aliases
and the starship prompt. Your own ~/.zshrc stays private and sources it, so
PATH tweaks, display scaling and anything personal never land in this repo.
Needs zsh + oh-my-zsh. install.sh clones the two
plugins if missing and appends one source line to ~/.zshrc (backup in
~/.zshrc.bak):
./zsh/install.sh
exec zshIn ~/.zshrc keep ZSH_THEME="" and
plugins=(git sudo zsh-autosuggestions zsh-syntax-highlighting).
Two layers: file names are coloured by LS_COLORS from zsh/darkgold.zsh,
and lsd/colors.yaml colours the other columns (permissions, user, size,
date, git status) with the nearest 256-colour matches to the palette
(187 cream, 144 brass, 173 salmon, 167 coral, 102 slate). lsd 1.0.0 (Pop
24.04) does not accept #hex here: one hex value makes it silently drop the
whole theme. install.sh backs up existing files to *.bak.
./lsd/install.sh
lsd -lbat/config is one line, --theme="ansi": bat uses the terminal's 16 ANSI
colours, so the COSMIC Terminal scheme themes it and it follows Harbor Light
too. zsh/darkgold.zsh aliases cat to it. install.sh backs up any
existing ~/.config/bat/config to config.bak.
./bat/install.shstarship/starship.toml is close to the defaults with a HH:MM clock on the
right. It uses the terminal's ANSI colours, so the COSMIC Terminal scheme
above themes it (the clock's yellow is brass #a99b7a). install.sh backs
up any existing ~/.config/starship.toml to starship.toml.bak.
./starship/install.shnvim/ carries the rice into Neovim: a dependency-free colorscheme built from
the palette (nvim/colors/darkgold.lua), a LazyVim spec that selects it and makes
sure the treesitter parsers for the files in this repo are installed
(nvim/lua/plugins/darkgold.lua), and a small RON syntax file so cosmic/*.ron
is coloured even before the parser exists. :terminal inside Neovim uses the
Harbor Dark scheme.
./nvim/install.sh
# restart nvim; LazyVim switches to the darkgold colorschemeWithout LazyVim, copy nvim/colors/darkgold.lua to ~/.config/nvim/colors/ and
run :colorscheme darkgold.
btop/DarkGold.theme uses the same palette: charcoal background, coral highlights, brass titles.
mkdir -p ~/.config/btop/themes
cp btop/DarkGold.theme ~/.config/btop/themes/
# btop → Esc → Options → Color theme → DarkGoldnala + flatpak updater. Headers are coral, success is cream, the figlet ramp is olive → gold → cream.
chmod +x scripts/update_system.sh
./scripts/update_system.shMakes this the active rice, coming from any other cosmic-*-theme rice. See
Switching rice.
./scripts/switch.shThe gitleaks pre-commit hook that used to live here grew into its own repo,
git-safety-net: the hook,
scan.sh for any repo's history, status.sh (am I protected?), a cheat sheet
and a walkthrough. Install it from there; this repo's .pre-commit-config.yaml
runs gitleaks on its own commits either way.

# secret scan on every commit, every repo: https://github.com/atraxsrc/git-safety-netThe installers replace what they own (with a *.bak copy), but some things
pile up instead: shell layers in ~/.zshrc, LazyVim specs, the updater link and
btop's theme setting. scripts/switch.sh makes DarkGold the active rice, coming
from any other cosmic-*-theme rice, and tidies those up. Every rice repo ships
the same script.
./scripts/switch.sh # switch, icons included
./scripts/switch.sh --keep-icons # leave the current icon theme aloneIt backs up every file it replaces, then:
- copies
cosmic/config/(fonts, terminal look, icons) and turns dark mode on. The terminal scheme and icon theme are only replaced when the current one is not already a DarkGold variant, so a dimmer text variant or another icon colour survives. Icons stay as they are until./icons/install.shhas run. - runs the fastfetch, lsd, bat, starship, Neovim and Claude Desktop installers and sets
btop's
color_theme - moves every other rice's LazyVim spec from
~/.config/nvim/lua/plugins/to~/.config/nvim/rice-off/(LazyVim loads every spec there and the last colorscheme wins); your own specs stay - comments out every other rice's
sourceline in~/.zshrc, and cosmic-ricing'sricing/zsh/colors.zsh, then uncomments DarkGold's or adds it - points
~/update_system.shat this repo's updater - installs the Firefox userChrome / userContent
The GUI steps it cannot do are printed at the end:
- Settings → Desktop → Appearance → Dark → Import
cosmic/DarkGold.ron - COSMIC Terminal → View → Color schemes → Dark tab → Import
cosmic-term/DarkGold-term.ron - Firefox: disable the old rice's add-on, enable this one, restart Firefox
- Settings → Wallpaper → a file from
backgrounds/ - Claude Desktop: Ctrl+Shift+T →
cosmic-darkgold, Appearance → Dark exec zsh, restart Neovim (:Lazy cleandrops plugins only the old specs used)
Skip 1 and 2 when that slot already holds DarkGold. The first time on this rice, run Setup once for the fonts, icons and cursor.
Within the pair (DarkGold ↔ White Gold): the two halves
sit side by side in COSMIC's Dark and Light slots and share one Claude Desktop
theme, so after the first time only the Firefox add-on and the wallpaper are
left by hand. Add --keep-icons to keep one icon colour across the pair.
Leaving DarkGold is the next rice's ./scripts/switch.sh. ./cursors/uninstall.sh
puts the Pop cursor back.
- Appearance → Dark → pick or import another theme
- Terminal → View → Settings → Appearance → Color scheme (dark) → another scheme
- Disable the cosmic-darkgold-theme add-on
- Cursor:
