Choose to work in light or dark mode.
The editor appearance will NOT affect the project/prototype’s appearance.
Project Appearance
Choose your project’s UI appearance: auto, light, or dark:- Auto: Your project will inhereit the UI appearance of the device they’re viewing your prototype on. i.e. Phones in dark mode will display the prototype in dark mode and vise versa.
- **Light: **Your project will always be in light mode, regardless of the user’s system UI settings.
- Dark: Your project will always be in dark mode, regardless of the user’s system UI settings.

The project appearance only matters if you’re using System Colors (primary, secondary background, etc.) or custom Color styles with defined light and dark mode.
