Overview

Mythos pairs Greek mythology-inspired UI palettes with matching editor schemes. Six dark choices and one light companion span cool navy, teal, violet, warm charcoal, and parchment.

Requirements#

IDE compatibility: IntelliJ IDEA 2025.2+. Check the Marketplace list for other editions and their supported versions.

The documented release is 2026.1.1. Its Marketplace compatibility starts at IntelliJ Platform build 252.0. Check the Marketplace compatibility list for your IDE edition and version before installing.

Install the theme in a compatible JetBrains IDE. No language compiler or language server is required. Modern Islands variants need the corresponding platform support; inspect the release compatibility and variant notes before choosing one.

Start here#

Install Mythos Theme, then follow Choosing a variant. The configuration reference explains where to adjust the behavior for your project.

In this manual#

Feature guides#

Visual guide#

• A tour of the seven Mythos palettes — Compare the myth-inspired dark families and light Elysium.

Customization#

• Accent families and editor schemes — Keep a Mythos variant coherent while customizing one part of the editor.

Current limitations#

Each variant has its own matching editor scheme. Switching only the editor scheme does not apply the full UI palette. The seven choices are independent themes rather than an automatic time-of-day schedule.

Release reference#

These instructions target the published 2026.1.1 release. Check the version under Settings → Plugins → Installed if your IDE behaves differently. For setup failures, start with troubleshooting.
