This property specifies a color for an object's background. This color is used when the BackgroundStyle property is configured to 1 (one, opaque) and one of the VerticalPercentFill or HorizontalPercentFill properties contains a value different from 100. Another use of this color is when the FillStyle property is configured with values between 2 (two) and 8 (eight). This forces the remaining area to use that background color for filling. In scripts, use VBScript's RGB method to create a color associated to this property. Default value of this property is gray (RGB(192, 192, 192)).
