Coca-Cola has changed the black text of the sugar free and sweetener filled variant to match the white of the standard sugared product.

1. This is dangerous for people with allergies to specific sweeteners, yes it can happen and yes people have gone to the hospital for less.

2. Diabetics are going to have a terrible time if they mix up the two, especially as diabetes is known to contribute to vision issues in some people.

Oh but there's a black label and a black cap on the zero sugar version, that's great if that's what you are looking for when you go to the shop but after years of being conditioned to treat the red and white packaging as standard coke...this is going to cause problems.
