Specifies the background color used when creating the raster image file.
Background Color displays a list of colors - black, red, yellow, green, cyan, blue, magenta, white, and "other." Other represents indexed and True Color (24-bit and 32-bit) output depths. The options are black, white, and other for grayscale, and black and white for monochrome. Select Other to display the AutoCAD Select Color dialog box.
If you are creating grayscale output, you must select a color from the Select Color dialog box.
