I having a lot of fun with superchile's as they are the easiest thing for me to grow. I do find thought that they ripen deep red. This season was a fun experiment as I grew from saved seed from last years plants. The experienced growers here told me that they would not grow true. I don't care. With 8 plants that I grew, I got 3 different pod types.
Type 1 - exactly the same as their parents. The others were shorter, fatter and grew facing down, instead of upright.
Type 2 - shorter, fatter and grow downward instead of upward.
Type 3 - Long, more traditional Cayenne type pods.
Type one and 2 are short bushy plants like their parents. They are also great producers. I only have 1 type 3 plant. It is a very tall plant, with 2 sections, splitting from a v shaped branch near the bottom. It has not been a good producer.
The heat level varies with type one and 2, but both are around the same heat level as the parent plants. Type 3 is much hotter.
