Overview

Andromeda is a dark, vibrant theme with coordinated syntax, panels, terminal colors, and rainbow brackets. Additional variants change the accent color while retaining the dark workspace.

Requirements#

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

The documented release is 2026.2.1. 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.

Current limitations#

These are dark variants, not light-mode alternatives. Rainbow bracket appearance also depends on the IDE’s editor configuration and any competing bracket-color plugin.
