Themes
Definer's appearance is fully customizable through themes. You can choose from default options, create your own designs with the built-in editor, or even set up automatic theme switching based on time of day using schedules.
Default Themes
Definer comes with four carefully designed themes to suit different preferences:
- Definer Light: A clean and bright theme for a fresh look.
- Definer Dark: A sleek and modern dark theme for low-light environments.
- Royal Blue: A vibrant blue theme for a touch of elegance.
- Calming Green: A soothing green theme for a relaxed experience.
Definer's default themes
Definer Light and Definer Dark are special persistent themes that cannot be edited, deleted, or reordered. However, if you want to make minor adjustments, you can create a new theme based on either in two steps:
- Activate the theme you want to customize
- Click the "CREATE THEME" button
Custom Themes
You can create your own themes using the built-in editor.
Royal Blue and Calming Green are technically custom themes (meaning you can edit, delete, or reorder them), but they come included by default.

- Secondary - For interactive cards and elements (should contrast with background)
- Accent - For highlights and emphasis
- Background - Most abundant color in the interface
- Primary text - A variant of primary color used specifically for text
- Text - Main text color (should be legible on both secondary and background colors)
- Contrast text - Text color that remains readable on elements using primary color as background
- Links - For hyperlinks and clickable text
- Success - For those satisfying "everything worked!" messages
- Warnings - For "proceed with caution" notifications
- Errors - For "oops, something went wrong" alerts
- Info - For neutral informational messages
