> ### Setting the Background Color

> When using reflections, the background color has a strong influence on the brightness of the objects, since many parts will reflect the background. Thus, it often makes sense in a raytracing setup to use a black background color.
> The background color can be set in the Preferences dialog.
> Click the menu entry
> "Edit->Preferences".
> Highlight Display->Main in the Entries list on the left.
> Next, press the Edit button in the Background Color box to change the background color.
> The black color is provided among the Basic colors.
> Confirm your color choice by pressing OK and apply the new preferences by pressing OK in the Preferences Dialog.
> Press Next to continue.
