Open Settings → Appearance to change how Portfolio Boss looks. Appearance controls change the display; they do not change a strategy’s trading rules.
Choose the theme and display size

- Choose an accent from the Colors palette.
- Choose Light, Dark or System Preference in the theme control. System Preference follows the operating-system preference.
- Choose a percentage under Scale. Increase it if controls and text are too small; decrease it to fit more on screen.
- Use Reset beside Scale to restore the normal scale. You can also hold Ctrl while turning the mouse wheel to resize the interface, or use Ctrl + middle-click to reset it.
Set trading-state and position colors

| Color group | Meaning |
|---|---|
| Trading State Colors | Customize the visual colors for Running, Paused and Warning. |
| Position Colors | Customize Default positions, Cash equivalent positions and Cash. |
| Reset Trading Colors / Reset Position Colors | Restore the corresponding group without resetting the other group. |
Use the text labels as well as color when identifying a state or position type. Choose distinct colors that remain readable in your selected theme.
