A dental color mixture indicator device is described. In an embodiment, the dental color mixture indicator device (420) comprises four component indicator devices (400-403) each retained by a common base (410). Each component indicator device (400-403) has an array of color samples (Y1-2,C1-3,R1-2) mounted to individual blades (430,440-442,450-452,460-462), with each group of blades able to be plucked from the base (410) for the purposes of a comparison with a tooth. Each color sample (Y1-2,C1-3,R1-2) corresponds with an artificial tooth material, and, on the basis of the comparison, a mixture of the respective tooth materials allows correct color matching of a restorative tooth. The arrayed color samples (Y1-2,C1-3,R1-2), coincide with a corresponding location on a color co-ordinate system. The central colors (201) of each component indicator device (400-403) are offset from other ones of central colors with respect to the color co-ordinate system. This means a fewer number of samples are required than in the prior art to encompass the whole body of tooth color.
