I remember pepsi blue existing but I don't remember ever wanting to buy it. I did probably try it at some point, but neither of the restaurants I worked at during those years carried it.

idk if it's the same thing but in the UK we had a limited run of "electric" pepsi a few months ago that was dyed blue, everyone I know assumed they were just trying to shift a bad batch as a limited edition drink.

It was sweeter. Like, you were expecting lemon-lime of Sprite or 7up, but you got the sugary caramel of Pepsi. Almost like clear cream soda, but without the strong vanilla flavor.

Tastes the exact same as regular Pepsi if I remember correctly

I remember it tasting just like Pepsi, but it was a little less syrupy in it's consistency. I loved the stuff as a kid.
