You’re in England?
(Gray is the American spelling; grey is the English spelling... though technically both spellings have been around for hundreds of years.)

“You’re in England?”
No, I was born and raised in the good ol’ U. S. of A. ;-)
The schools I attended as a child taught that “g - r - e - y” was the correct spelling of the color and that “g - r - a - y” was colloquial and used only by the uneducated.
