Carbon black (Color Index International, PBK-7) is the name of a common black pigment, traditionally produced from charring organic materials such as wood or bone. It appears black because it reflects very little light in the visible part of the spectrum, with an albedo near zero.
The word 'black' when used in this context means covert, undercover, not seen. When a person enters the intelligence community and becomes involved in operations and projects, all their government files basically disappear. They are no longer accessible through the normal channels.
