Red and Green are colors with an inherent value (at least, in the US), suggesting good and bad. Unless there's a reason that they're the colors they are, you should use a color (I'd suggest a dark gray) that doesn't have a specific value.

I normally rail against pie charts, but in this case, you're comparing a part (calories in the serving size) to the whole (recommended calories per day), so I'm okay with it.

But the bigger thing I'd want to comment on: If you're redesigning the label, REALLY redesign it. Show the volume of the serving suggestion with a photo on a standardized plate / bowl. Or bring in some other piece of data that helps people make decisions. Do something wholly different with it. (Basically, what DanielStraight said.)

Aside from the pie chart and Christmas colors (which I can't figure out the logic of intuitively), I don't see what's much different, and since we know that people are terrible at reading pie charts, I don't see how the pie charts will help.

I would like to see numbers per 100 g, or some other standard that can be compared across foods. I would also like to see a nutrient density score of some kind.
