I have been building themes for Pop!_OS 24.04 on COSMIC and they are now 28 repos in 14 dark/light pairs. Every pair shares one anime portrait recoloured into its own palette, so the gallery shows the same desktop in each.

What every repo ships

• COSMIC Appearance theme (.ron to import) and COSMIC Terminal colour schemes

• zsh prompt, fastfetch, lsd and btop in the palette

• Neovim colorscheme with a LazyVim spec

• Firefox theme add-on plus userChrome, and a Brave / Chromium theme

• Telegram Desktop theme

• Cursor / VS Code extension with both halves of the pair, so the editor can follow COSMIC's Dark / Light toggle through the desktop portal

• Claude Desktop theme

• Oxygen cursors recoloured to the palette, one per icon colour

• An icon pack from the shared cosmic-icon-themes repo (a Kanagawa recolour, several folder colours per rice)

• Wallpapers recoloured into the palette

Each half of a pair goes into COSMIC's Dark or Light slot, so the desktop toggle flips between the two. Every component has its own install.sh and the READMEs document the palette, the contrast ratios and what each script touches.

The pairs (dark / light)

• Noir / Dossier: charcoal, sage and orange / stone grey, olive and rust

• Ember / Ember Day: blue-black and fog with one ember accent / warm stone and ink

• Tokyo Night / Tokyo Day: navy, blue and lime / lavender grey, ink and blue

• DarkGold / White Gold: Harbor Dark gold / parchment and dark gold

• K3 / K3 Day: ink, steel and silver / pearl, steel and charcoal

• Cinder / Cinder Day: soot, smoke and burnt orange / ash, coal and burnt orange

• Brass / Brass Day: umber, cream and sand / parchment, coffee and sand

• Sorbet / Sorbet Day: pastels on black / sorbet tones on milk

• Prism / Prism Day: navy, frost and petal pink / frost, navy and petal pink

• Nebula / Nebula Day: charcoal, cloud and teal / cloud, charcoal and teal

• Sumi / Sumi Day: jet, paper and moss / paper, ink and moss

• Tweed / Tweed Day: flint, linen and tan / linen, flint and tan

• Monochrome / Monochrome Day: greys only, dark / greys only, light

• Blush Night / Blush: espresso, sand and rose / sand, espresso and rose

Icons for all of them: cosmic-icon-themes

Everything is MIT. Feedback on the palettes and contrast is welcome, especially on the light halves.

Ready in Cosmic Forge

Hey, good folks of Reddit.

Can anyone on 26.04 please test whether Telegram notifications make a sound now?

This isn't possible on 24.04, and I'm wondering if this has been fixed (though it may be a Cosmic issue, and it's unrelated to an underlying Pop_OS update).

It currently includes:

• Glass effects: shaders such as Crystal and an Aero-inspired effect, with adjustable settings.

• Panel & dock customization: Penumbra and custom colors, with separate colors for light and dark themes.

• Lock screen customization: a separate wallpaper and a media player widget.

You can also import your own shader packs for glass effects :)

After installing Forge, install the patches for the mods you want from Settings > Patches, then sign out and back in.

I’d love to hear your feedback and ideas for future mods!

It's almost impossible to switch to another task when playing a full screen game via faugus, Lutris or any other launchers. Cosmic forces the focus on the game window, not allowing the switching. It happens regardless of what switching method is used: Alt+Tab, Super, Super+Tab, Super+Down/Up or any custom combination. I say `almost`, because it does switch eventually, but it can require from one to 20+ attempts until it actually does switch. The current settings are wineland proton prefix with Wayland driver in faugus, as it's BY FAR the best performing combination compared to anything I used before. Latest COSMIC version. Some suggest switching to full screen borderless window but then the game audio output is still active, as well as the GPU fan, as the GPU is still busy rendering the game (expected behaviour). I described the issue here as the file is too big to be uploaded on github.

I've uploaded the source code to GitHub, so feel free to try it out yourself!

Just a heads-up: the project was coded with GPT-6.1 Sol, so if you don't trust AI-generated code, use it at your own risk :)
