Lucky Charms feeling a little less blue
If there was any confusion with the two brands, that should now be lessened. I just spotted an updated version of Lucky Charms Frosted Flakes with a much lighter blue background and different lettering. These new boxes have begun to appear without any fanfare or announcement from General Mills.
So why did they go with this redesign so quickly after launch? Most likely Kellogg put pressure on them, warning them that it was too close to their Frosted Flakes design scheme (even though Frosted Flakes as a name is not a registered trademark). The less cynical might think this was intentional, to create less confusion between the two cereals.
In any case, scoop up some boxes of the original, dark blue version. They could be a collector items some day!
