I've never come across the "olive" variety. Fox peppers also offers a "golden" one.
In my experience (tropical lowland conditions), consistent watering is important. I have the occasional pepper plant that suffers from BER (mostly annuum, I think), but growing tomatoes in containers and keeping them BER-free is a challange. I have to water them a bit every day.
The pose/composition of Pepper lover girl b would have been my favourite if it weren't for the malformed hand. A somewhat strange torso as well, with adipose tissue were it shouldn¡t be.
