1. A computer-implemented method for specifying a material color of a dental restoration, the method executable by an electronic device comprising a computer, smartphone or tablet having a processor and a user interface comprising a keyboard and/or screen and/or mouse coupled to the processor, said method comprising
a desired tooth color is entered via the user interface as a target tooth color, said target tooth color being the tooth color of a neighboring tooth, said target tooth color specified as the material color of the dental restoration,
upon specification of the material color of the dental restoration starting from the target tooth color the material color of the dental restoration is changed based on one or more parameters selected comprising a color of a stump, a color of an abutment, a layer thickness of the dental restoration, a type of dental restoration, a material of the dental restoration, or a processing technique,
wherein, once one of the one or more parameters is selected, a next parameter is offered automatically to the user interface, wherein the selection is limited based on parameters which are dependent on one another,
wherein, when all selections have been selected, a display of a result of the material color is generated onto the screen, and
wherein the dental restoration is prepared based on the result of the material color.
