I'm trying to set the DefaultValue for a property in a custom control but cant figure out how to set it for a color.

<Category("Thumbnail Pannel"), _
           Description("Back Color of Selected Thumbnail"), _
           DefaultValue(System.Drawing.Color.Blue)> _
       Public Property SelectedThumbBackColor() As Color

I get an error "Constant expression expected".
Anyone know how to set this up for a color?

Thanks
Brian Grant
