You are 100% right, but I have an M.A. in English from a Crappy College. And, my poetic license from there allows me call it "style" like using the conjunction "And" at the beginning of a sentence (like I just did) and fall back on the British spelling of Grey. LOL. I am very appreciative of the correction. Sincerely. To prove it I have custom-made an upvote to assuage my sin.
