This property specifies a fill color for this 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 has a value different from 100. Another usage of this color is when the FillStyle property is set to values between 2 (two) and 8 (eight). This allows the remaining area to use that background color for filling. In scripts, use VBScript's RGB method to create a color to link to this property. Default value of this property is gray (RGB(192, 192, 192)).
