Noctis

Unofficial IntelliJ Platform port of Noctis by Liviu Schera — a collection of light and dark themes with a well-balanced blend of warm and cold medium contrast colors.

Plugin ID: com.manvendrask.noctis.jetbrains
Display name: Noctis
Compatible with WebStorm, IntelliJ IDEA, PyCharm, and other IntelliJ-based IDEs 2025.3+.

This is a stand-alone theme plugin. It is not affiliated with the original VS Code extension.

Themes

Each of the 11 upstream palettes is registered twice:

Islands (2025.3 look)	Classic (pre-Islands chrome)
Noctis Islands	Noctis Classic
Noctis Azureus Islands	Noctis Azureus Classic
Noctis Bordo Islands	Noctis Bordo Classic
Noctis Obscuro Islands	Noctis Obscuro Classic
Noctis Sereno Islands	Noctis Sereno Classic
Noctis Uva Islands	Noctis Uva Classic
Noctis Viola Islands	Noctis Viola Classic
Noctis Minimus Islands	Noctis Minimus Classic
Noctis Lux Islands	Noctis Lux Classic
Noctis Hibernus Islands	Noctis Hibernus Classic
Noctis Lilac Islands	Noctis Lilac Classic

Islands variants inherit Islands Dark / Islands Light. Classic variants inherit ExperimentalDark / ExperimentalLight.

Requirements

• JDK 21+
• Node.js 18+ (only to regenerate theme files)
• Gradle 9.3.1 (wrapper included)

Build and try in WebStorm

./gradlew buildPlugin

The installable ZIP lands in build/distributions/. In WebStorm:

1. Settings → Plugins → gear → Install Plugin from Disk…
2. Choose the ZIP
3. Restart when prompted
4. Settings → Appearance & Behavior → Appearance → Theme and pick a Noctis variant

The editor color scheme is wired through each theme’s editorScheme, so syntax colors switch with the UI theme.

Sandbox WebStorm (fast iterate)

./gradlew runIde

This downloads a WebStorm 2025.3 sandbox and launches it with the plugin loaded. Sign in with your JetBrains account if the sandbox asks. A second task, runWebStorm, is registered the same way.

Open the files under samples/ (JS, TS, HTML, CSS, JSON, Markdown) to check syntax colors.

Visual QA checklist

Do this for at least one dark Islands theme (Noctis), one dark Classic theme, one light Islands theme (Lux), and one light Classic theme:

• Editor tabs: active, inactive, dirty
• Project tool window, terminal, Git diff, Find in Files, completion popup
• Settings dialog, notifications, debugger
• Optional: enable Internal Mode (idea.is.internal=true in the sandbox VM options) and use Tools → Internal Actions → UI → UI Inspector / LaF Defaults for unstyled keys

Regenerating themes

Palettes are vendored from the sibling noctis VS Code repo:

# If ../noctis is present (this checkout’s sibling):
node tools/extract-palette.mjs

# Always:
node tools/generate.mjs

Or ./gradlew vendorPalette generateThemes. Generated files live in src/main/resources/themes/ and src/main/resources/META-INF/plugin.xml. Do not hand-edit those; change tools/generate.mjs or the palette snapshot instead.
