Custom Themes

>=4.5

Custom themes let you adapt massCode to your workflow and visual preferences. You can change both the app UI colors and the editor syntax highlighting colors.

How it works

• Themes are stored in ~/.massCode/themes/ as JSON files.
• Both light and dark theme types are supported.
• Theme files are watched in real time — edit the JSON, see the result instantly.

Creating a Theme

Create a new theme from Settings → Themes. massCode generates a Rose Pine-based JSON template that you can use as a starting point and edit in real time.
