> > It's a British/American difference. "Grey" is the British spelling, and "gray" is the American spelling. You're right that the two different spellings seem to carry too different connotations. "Gray" doesn't seem boring to me, but "grey" does seem more interesting.

> Seeing 'gray' as the less interesting spelling I'm reminded of a burst of joy I encountered while reading the dictionary. I used to deliver Chinese food and know well that little stars next to a food item mean that the food is Hot and Spicy. Well, when looking through the dictionary, I saw these same stars next to some of the words. I'm thinking to myself, "What are these hot and spicy words?" I felt great national pride upon discovering they were the words with American origin. Not only is 'grey' more interesting, in my book, its got a little more zing.

I just realized that I use grey and gray interchangably. In most other cases where I use two spellings of the same word there is a difference. For example, a theater is where I go to see movies and a theatre is where I go to see plays. That's not official. It's just the way I use them. It might also be worth pointing out here that sometimes I make up spellings as I go along.
