Remarks

The Colors property can be used with the following parameter.

Parameter	Description
Index	The index number of a color in the workbook color palette (from 1 to 56). If this argument is not specified, this property returns an array that contains all 56 of the colors in the palette.

If you attempt to use Colors without specifying any parameters, Colors will get a _ColorsType object that is part of the Office development tools in Visual Studio infrastructure and is not intended to be used directly from your code.

Optional Parameters

For information on optional parameters, see Optional Parameters in Office Solutions.

Examples

The following code example uses the Colors property to set the first color in the workbook's color palette to blue, and then programmatically displays the Microsoft Office Excel Color Palette dialog to verify that this change was made.

This version is for an application-level add-in.

Private Sub SetFirstColorInPalette()
    Dim vstoWorkbook As Workbook = Globals.Factory.GetVstoObject(Me.Application.ActiveWorkbook)
    vstoWorkbook.Colors(1) = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Blue)
    vstoWorkbook.Application.Dialogs( _
        Excel.XlBuiltInDialog.xlDialogColorPalette).Show()
End Sub

private void SetFirstColorInPalette()
{
    Workbook vstoWorkbook = Globals.Factory.GetVstoObject(this.Application.ActiveWorkbook);
    vstoWorkbook.Colors[1] = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Blue);

    vstoWorkbook.Application.Dialogs[
        Excel.XlBuiltInDialog.xlDialogColorPalette].Show();
}
