Quick Answer. The main cause of a purple tinge in fingernails is low oxygen levels in the blood. This can be caused by poor circulation, as well as habits that inhibit oxygen absorption such as smoking. A single fingernail may also become purple if it has been injured, indicating a bruise underneath the nail.
