The Best Dark Mode Skins for Hermes Agent

Most Hermes users live in the terminal for hours at a time, so a comfortable dark theme is not just an aesthetic choice — it is an endurance upgrade. The good news is that the Hermes skin engine makes switching themes trivial, and the community has built dozens of dark Hermes skins ranging from soft pastels to neon cyberpunk.

This post curates ten of the best dark mode skins on hermesskins.io. Every skin here is available now, free to install, and works with a single /skin <name> command inside Hermes.

How to preview a skin instantly

Each skin below can be activated for the current Hermes session by running:

If you want to make a skin your default across restarts, add it to ~/.hermes/config.yaml:

Ten dark Hermes skins worth trying

1. Catppuccin

Catppuccin is the gentlest entry point for dark Hermes skins. It pairs mauve, pink, peach, and lavender pastels on a warm dark base, with a small ASCII cat tucked into the banner. It is easy on the eyes during long sessions and still colorful enough that the interface never feels flat.

/skin catppuccin

2. Pirate

Pirate is a high-contrast black-and-white theme with pirate-flag ASCII art and a "no quarter given" attitude. It is the closest thing to a monochrome coding theme in the Hermes skin catalog, and it works well if you want the interface to stay out of your way.

/skin pirate

3. Empire

Empire turns Hermes into a Galactic Empire terminal: deep space black, canon reds, Death Star firing controls, and hologram-blue accents. If you want your agent to look like it is running on a Star Destroyer, this is the most detailed sci-fi skin available.

/skin empire

4. Neonwave

Neonwave is pure synthwave energy: hot pink and electric cyan on void purple, with a perspective-grid horizon rendered in braille art. It is the right pick when you want the terminal to feel closer to an album cover than a system prompt.

/skin neonwave

5. Netrunner

Netrunner is a cyberpunk hacker aesthetic built around cyan ICE-breaking colors, a skull braille-art piece, and neural-cable detailing. It is brighter than Empire but still firmly dark, and the cyan accents make status text easy to scan.

/skin netrunner

6. Vault-Tec

Vault-Tec mimics a Fallout terminal: green phosphor CRT on black with chunky ASCII branding. It is a nostalgic green-on-dark option that feels like booting into an old mainframe, and it keeps the color palette minimal so fatigue stays low.

/skin vault-tec

7. Skynet

Skynet is a menacing red-on-black military-AI theme with pyramid braille art. It is less playful than Empire and more ominous than Neonwave — a good fit if you prefer your terminal to look slightly dangerous.

/skin skynet

8. Lain

Lain is a Serial Experiments Lain-inspired digital-consciousness theme: hot pink on black with NAVI computer braille art and a Wired-protocol vibe. It is one of the more stylized dark Hermes skins, and it stands out without becoming unreadable.

/skin lain

9. Mother

Mother channels the Weyland-Yutani MU-TH-UR 6000: amber CRT phosphor, a HAL 9000 red eye, and terse corporate-AI energy. It is a warm dark theme rather than a cold one, which can feel easier on the eyes late at night.

/skin mother

10. Cyberpunk Anonymous

Cyberpunk Anonymous is the newest voice in the list: Matrix green, signal magenta, and surveillance-void black with a mask motif. It is loud, opinionated, and a strong choice if you want your terminal to look like it belongs in a dystopian net-cafe.

/skin cyberpunk-anonymous

How to create your own dark Hermes skin

If none of these quite match your setup, Hermes makes it easy to build a custom skin. You only need a YAML file with your colors, banners, and spinner art. The How to Create a Custom Hermes Skin guide walks through the file format with a minimal working example.

You can also start from any skin on this list: each item page links to a downloadable .yaml file you can open and edit.
