MATLAB Theme Extensions enhance MATLAB’s built-in themes by enabling users to create, import, and share custom color themes. This extension allows you to personalize your MATLAB environment and easily switch between different color schemes.
- Import custom color schemes from JSON files stored under the schemes folder (e.g., the Cobalt scheme):
import_scheme('schemes/cobalt.json');- Export your current color settings (including with the MATLAB Theme) to a JSON file:
export_scheme('exampleCustomColors.json');- Reset color settings by importing the default color schemes schemes/matlab-light.json and schemes/matlab-dark.json.
The project works by customizing colors on top of the existing MATLAB Themes (either Light or Dark).
Scheme files are JSON documents that must include a DesktopTheme field and follow the structure of the provided template.json in this project. Customizable fields include:
- Background Color
- Text Color
- MATLAB Syntax Highlighting Colors
- Output Colors
- Programming Tools
- Syntax Highlighting for other languages such as C, Java, HTML, etc.
- Current Line Highlight
- Right-hand Text limit line
- Boolean fields to enable or disable specific customizations
The fields in the JSON file are inspired by MATLAB's Settings panel (previously Preference Panel), see MATLAB Toolstrip → Home → Settings
