    Abstract: The invention relates to a method for determining an index for characterizing a quality of a matching color tone of a paint in relation to a color reference, characterized in that colorimetric coordinates of the paint and of the color reference are determined for a number of measuring geometries using a spectrophotometer, color differences are calculated from the colorimetric coordinates of the paint and of the color reference for each of the number of measuring geometries and are normalized, and a pre-established assignment rule is used for assigning a value on a scale to a group of characteristic values calculated from the normalized color differences in order to determine the index.

    Abstract: There is provided an illumination device from which an index can be obtained, the index appropriately reflecting intensity of a light beam guided to an object to be illuminated. A light source, a photodetector, and a support structure are provided in the illumination device. The light source emits light. The light source has light distribution in which a reference axis serves as an axis of symmetry or light distribution in which a plane including the reference axis serves as a plane of symmetry. A first light beam included in the light is guided to the object to be illuminated. A second light beam included in the light is guided to the photodetector. The photodetector detects intensity of the second light beam. The light source and the photodetector are supported by the support structure in positions and postures that allow the first light beam and the second light beam to be guided in an aforementioned manner. A traveling direction of the first light beam makes a first angle with the reference axis. A traveling direction of the second light beam makes a second angle with the reference axis. The second angle is the same as the first angle.

    Abstract: The invention relates to a computer implemented process for matching a paint to the visual appearance properties of a painted substrate surface comprising the steps of a) selecting a potentially matching first candidate paint based on a first paint recipe comprising one or more colour and/or effect imparting toners, b) applying the first candidate paint to a test panel to obtain a first painted test panel c) visually comparing the appearance properties of the painted substrate surface and the first painted test panel under more than one viewing angle, wherein the visual comparison comprises c1) selecting a visual appearance category wherein the appearance of the painted test panel most prominently deviates from the painted substrate, wherein the categories are selected from a number of pre-defined visual appearance categories displayed on an output device of a computer, c2) inputting the selected visual appearance category in an input device of the computer, c3) visually determining the visual appearance difference of the painted test panel and the painted substrate in the selected appearance category, d) entering the determined visual appearance difference in an input device of the computer, e) optionally, entering only the types of toners of the candidate paint in an input device of the computer, f) providing a paint recipe modification advice consisting an advice of increasing or reducing one or more of the toners in the recipe, or adding an additional toner to the recipe or, on an output device of the computer, wherein the computer software provides the modification advice on the basis of i) the entered visual appearance difference and ii) a database in which only visually determined appearance properties of available toners under two or more viewing angles are stored, with the aim to minimize the appearance difference, g) preparing a second candidate paint based on the recipe modification advice, h) applying the second candidate paint to a test panel to obtain a second painted test panel, and i) repeating steps c) to h) until the visual comparison in step c) indicates that the candidate paint sufficiently matches the appearance properties of the painted substrate surface.
