Lamp black takes its name from its method of production. Fine soot was collected and prepared as a colourant for inks and paints. It is an example of a historic pigment made through a process, rather than simply dug from the ground.
Fine carbon particles absorb light and create black. In mixtures, black can lower lightness and mute stronger colours; the resulting undertone depends on the particular black and the other ingredients.
Modern carbon blacks have varied manufacturing routes and particle characteristics. The traditional name is not a guarantee of the production method used today, nor evidence that all black pigments are interchangeable.
