The orange is normal. Baby poops come in an amazing array of colors because their digestive tract is immature and doesn't digest everything. Carrots and sweet potatoes make things orange, and stain the skin. Blueberries are the best - you get green poop from that! Not to mention purple gatorade or grape pedialyte.
The acidity of the fruit can aggravate the skin. It doesn't necessarily mean that there's an allergy, but the extra sugar in fruits can exacerbate the problem because of the large amount of sugar tends to make bacteria and yeast grow (and therefore be excreted) so it can aggravate the skin. Yeast looks like a pimply rash, and bacteria or acidity is just general redness.
The best thing to do is to coat the bum at every diaper change with a diaper rash preventing cream. I like Maalox+aquaphor+antifungal cream mixed in even parts because you get the protection of the aquaphor, the acid reduction from the Maalox and yeast prevention from the antifungal.
Most food allergies show up in a rash elsewhere on the body, as diarrhea, or as a fever or respiratory problems. Redness around the bum isn't a usual allergy signal.
