Stop.spelling coloring that way. I find it profoundly disturbing and it scares me.
It's a Canadian thing; probably English too. After I moved here and got a job as a reporter, I always found it odd when my editor wanted me to stick in an extra "u" when it's really not necessary.
Just like calling the last letter of the alphabet "zed" and not just a plain "z", eh, OttawaFreeper? ;) (btw, I live just across the river from you; let's not even get started on the "Francophonie." LOL! Have a great day, both of you; I'm just kidding around. :) )
