Ayu Mirage Theme

Install

Version: 1.0.3
Publisher: HarborClient
Appearance: Dark
Repository: https://github.com/harborclient/theme-ayu-mirage (v1.0.3)
Permissions: ui
Homepage: https://github.com/harborclient/plugin-ayu-mirage

Cool slate backgrounds with a warm gold accent and soft coral highlights — Ayu Mirage’s balanced, easy-on-the-eyes dark palette.

This is a JSON-only theme plugin: HarborClient loads the palette from exported.json via contributes.themes[].import. No JavaScript entry or build step is required.

Permissions

Package layout

ayu-mirage/
├── manifest.json      # contributes.themes[].import → exported.json
├── exported.json      # harborclientExport: "theme" envelope
├── README.md
├── screenshot.png
└── signature.json     # publisher signature (from pnpm release)

If you later add a sibling CSS file and set "stylesheet": "styles.css" in the export, HarborClient inlines that CSS into exported.json on first read so the theme stays a single self-contained file.

Usage

Enable the plugin, then choose Ayu Mirage from the Appearance dropdown.

Requires HarborClient >=2.5.0 (theme JSON import).

Development

In HarborClient, open File → Themes (or Settings → Plugins) → Load unpacked… and select this project folder
Enable the plugin and select Ayu Mirage under View → Theme or Settings → General → Appearance

Edit colors in exported.json and reload the unpacked plugin to preview changes. No pnpm build is needed.

Packaging

pnpm pack

Creates ../ayu-mirage.hcp with manifest.json, exported.json, README.md, screenshot.png, and signature.json.

├── README.md

Development

In HarborClient, open File → Themes (or Settings → Plugins) → Load unpacked… and select this project folder

After the first load inlines the CSS, edit the inlined stylesheet string in exported.json (or restore "stylesheet": "styles.css" and keep a sibling CSS file for iteration).

Packaging

pnpm pack

Creates ../catppuccin-latte.hcp with manifest.json, exported.json, styles.css, README.md, screenshot.png, and signature.json.
