Colour vision deficiency is often called colour blindness. If it is compounded of multiple parts cemented together, each of these parts is considered an element, the whole is called a group. Once the industry figured out how to manufacture a mirror that could swing up out of the way during exposure, the second lens could be eliminated, taking with it the parallax and extra weight and bulk that TLRs required.
