But then why does

   Grid[Join[{{"First", "Second", "Third"}}, Partition[Range[6], 3]],
        Dividers -> {{Green, 2 -> Red, 3 -> Red}, {2 -> Blue}}]

work as expected?  Why is it OK to mix the two types of specifications 
when the first item is Green but not when the first item is None (or False)?
