If you are talking about pods that have a white or whitish stage before they ripen, I can think of a few:
Â
Aji Omnicolor
Â
Barra Do Ribeiro
Â
Bishop's Crown Multicolored
Â
All of these have pods that start out a whitish or cream color, before turning other colors on their way to red.
Â
There is also the White Aji Fantasy, and the "Sparkly White" Aji Fantasy, that ripen to a whitish color.Â
