I hadn't opened a pack of Wrigley's Spearmint in many years and was surprised to find that it's now green instead of off-white. When did that happen? Also, it seems odd that the packaging shows a double-pointed arrow — that visual device had always been reserved for Doublemint gum, while Wrigley's Spearmint always had a single-pointed arrow. Not sure when this changed, but I find it strangely upsetting, as if one of the universe's eternal verities has been upended.
(Special thanks to Mary Bakija for suggesting this one.)
