You can define which color you want to use for dimensions, labels, background, and grid lines in the model. For example, if you set the background color to black, you may need to adjust the other color settings as well to ensure that the text and dimensions will be visible.
Change the color settings in the Advanced Options dialog box using RGB values on a scale of 0.0 to 1.0. Separate the values with spaces. For example, the color code for yellow is 1.0 1.0 0.0.
