This property specifies a fill color for an object's background. This color is used when the BackgroundStyle property is set to 1 (one, opaque) and one of the VerticalPercentFill or HorizontalPercentFill properties is different from 100. In scripts, use VBScript's RGB method to build a color to link to this property. The default value of this property is gray (RGB(192, 192, 192)).
