It is nteresting that the website given is in the UK, where (at least in certain areas) orange already has some, uh, connotations.

I imagine they were probably more thinking along the lines of saffron robes of monks (side note, I always pictured saffron as being a golden tone, like the spice turns rice, and I was surprised when I went to see Christo and Jean-Claude’s Gates in Central Park and they were old-school-lifejacket-orange), but the fact is there are an awful awful lot of Irish folks who are going to have a hard time jumping on that bandwagon.
