A black tattoo cannot be covered by any other colors, as the lighter colors will not be able to mask the density of the black ink. However, a new and larger design using black ink can be used to cover an old black tattoo.
Generally, small tattoos are simple to cover up with a new design, and it is possible to incorporate pieces of an old tattoo into a new design, especially when red and orange pigments are present. Additionally, tattoo removal using laser technology is an alternative option for people with large black ink tattoos that are unable to be covered by a new tattoo. The course of action is dependent on the person, thus a tattoo artist should be consulted to discuss viable options for the tattoo at hand.
