Nucleus supports three display modes. Your preference is saved to your account and persists across sessions.
Changing the Theme
- Go to Settings in the sidebar.
- Click the Appearance tab.
- Select one of the three options:
| Mode | Behavior |
|---|---|
| System | Follows your operating system preference. If your OS switches to dark mode at night, Nucleus follows. |
| Light | Always light background, dark text. |
| Dark | Always dark background, light text. |
The change takes effect immediately — no page reload required.
The default setting is System, which automatically matches your OS preference.
