As I am going across the ocean tonight for 2 weeks to study in Cambridge, I was packing my suitcase when it occurred to me that the word "color" has a 'u' in it in their version of English.

So which one is better to use EoFF, color or colour? Firefox says color is better, but Firefox also said Ivysaur is not a word so I have some apprehension blindly following it, and the internet HAS to know the answer.
