Murray,
It does seem complicated! And it does look like something of a bug. I think
the last item for spec_i choices is the key.
{spec,rules} use rules to override specifications in spec
Grid[Join[{{"First", "Second", "Third"}}, Partition[Range[6], 3]],
Dividers -> {{None, {2 -> Red, 3 -> Red}}, {2 -> Blue}}]
None specifies no vertical dividers but the second list overrides specific
positions.
However, it is not necessary to specify None because if we use a list of
rules then they are the only dividers that are drawn.
Grid[Join[{{"First", "Second", "Third"}}, Partition[Range[6], 3]],
Dividers -> {{2 -> Red, 3 -> Red}, {2 -> Blue}}]
