They definitely have differences in flavor, I had an executive chef that absolutely hated green bell peppers. The “underripe” green bell is much more vegetal than it’s sweeter, ripened red form, which has had more time to develop natural sugars. Like a banana. In fact, peppers and bananas are both technically berries, botanically speaking! Raspberries and strawberries aren’t though? lol
I’ve only seen red, yellow, and green bell peppers. Maybe orange
Red, orange, yellow and green are all the same varient, but at different ripenesses. The others are different varients.
Mostly just a novelty. Throw in a bit more colour, if available.
Maybe I’m dumb but I sampled all of them raw and orange definitely taste the best.
