I have a potted kale plant in my completely dark root cellar. it continues to produce new leaves, that are green. Except for an incandescent bulb turned on 5min./month it gets not light. Is it producing new chlorophyll? How can the leaves turn green?

The new leaves are still producing chlorophyll since that is part of its genetics, especially for the high chlorophyll content in kale. The chlorophyll gives the leaves their green color.
