In a shade determination apparatus for teeth and dental restorations, a set of reference templates for comparing to a patient's tooth is provided, whereby based on the coloration of the reference template the shade of a tooth or of a restoration to be employed can be determined. The reference templates are produced in a layer arrangement, taking into consideration layer thickness and/or material selection, that corresponds to the tooth or the dental restoration to be employed. A storage apparatus stores the coloration of the reference templates, and the layering of the tooth or of the dental restoration can be matched and determined based on partial images from an image of the patient's tooth.
