Red, green, and yellow bell peppers. Is color the only difference?

[jet'adoretoujours]

Is there any nutritional difference between these peppers?
Also, they all taste the same to me, so why do recipes call for one and not the other(s), or just leave pepper choice as arbitrary?

No, they all taste different. Green is more rough tasting......red is less so, and yellow and orange you can eat raw really. (red too but yellow and orange are easier).

Red and yellow peppers are ripe green ones haven't turned yet. The ripe ones typically have a sweeter taste. But mostly I choice what I want based on the color appeal of what they are being mixed with

There must be something different about them, since I'm only allergic to green bell peppers, no other kind of pepper!
