Orange is every bit as much an Irish colour as Geeen, as any glance at the Irish flag will demonstrate. And that's why the flag was made that way.

True enough there's been a bit of a tribal dispute about what political arrangements would be the best way to organise things on the shared island, but that's a temporary disagreement which can't last that much longer - another one or two generations. But Green or Orange, both sides are Irish, and the day belongs to both of them equally.
