The Apparatus for determining the color stimulus specification of a translucent object, for example of a tooth, comprises an illumination device as well as an image capture device. For illuminating the object under test with light in different wave length portions, the illumination device comprises an LED array with a plurality of sequentially energizable light emitting diodes. Several different types of light emitting diodes are provided, each emitting light in a different wave length portion.
