The development of colour effects in plastic materials is both more advanced and less costly than it was even a few years ago. Good resistance to fading and weathering is obligatory, and coatings are increasingly unnecessary. It is also important to remember that the optical impact of effect pigments depends on the angle: accordingly, a colouristic assessment therefore needs to be made from several viewing angles. For a visual comparison, this is easily done: the material samples to compare are simply tilted back and forth. For a colorimetric assessment, conventional colour analysis equipment is unsuitable, as it can only measure from one angle. Colour analysers for assessing effect pigments are capable of measuring colour from up to ten angles, however.
