Very strange indeed. I am not sure why the red and yellow peppers would do that if the green ones are fine. The only things that come to mind is:
Perhaps those peppers are in different soil conditions (dryer, wetter, contaminant in the soil)
Perhaps those peppers were sprayed with something that burned the foliage.
Perhaps those varieties are more prone to foliage or root diseases.
I suggest you take some photos and leaf samples or an entire plant sample to your local County Extension Office for them to look over and diagnose. Their contact info is:
