I don't even know who the Packers are. I had to google it. I'm not even from the US
You spell "colors", "colours". Don't even have to look at your profile to tell you're from the U.K. Does the spellcheck over at GMT try to make you spell "theatre", "theater" or "centre", center? Does it recognize "lorry" as a word? Has old John Bull ever changed his underpants or does he even wear any?
None of these questions are pertinent to anything.
BTW, theatre and lorry both passed my spellcheck over here in CST, but not centre or colour.
