It seems all kinds of products are getting into the habit of modifying colors to align themselves with holidays or seasons, hoping to increase sales. I’d say the tactic probably does work. I know that I find myself buying more holiday versions of candy, in particular. Oreo actually started their version of holiday or seasonal varieties several years ago but this was the first time in a long time that one of the colorful versions induced me to purchase. I guess I may have needed a splash of sunshine so when I saw the yellow-filled "Spring" Oreos I bit.
I actually find them a bit disconcerting to eat. The brightly colored yellow fillings seem like they should be lemon flavored. But they are not. Instead they are just the "regular" flavor. Still that doesn’t seem to have actually slowed down my consumption. I just have to squint a little when I take the first bite so I screen out the lemon vibes I get from the yellow filling.
