gray or grey?

[nittanyalum]

So all the bickering threads lately invariably seemed to mention a "gray/ey area" here or there. I noticed how many people used the "-ey" spelling and since I don't feel like even looking at the "heavier" threads right now I thought I'd start a totally simple one.

Do you spell the color g-r-a-y or g-r-e-y?

I'm an "a" girl myself. Gray.
