Hm... this whole orange thing is interesting and reminds me of the Orange Catholic Bible featured in Dune. Frank Herbert (author) was raised Catholic, but American -- his novel The White Plague takes place in Ireland, so I'm wondering if there is a family connection there. However, Dune takes place 8000 years in the future, so it's certainly possible that he did some combination thing of Protestantism and Catholicism for his own purposes. (This is by no means a major feature of the novels, only a very minor component. But I was always curious about the "orange" part.)
