In addition to the aesthetics of the packaging and the coherence of the design, colors are also important. They identify a product and characterize its quality, for example in terms of food, paints, surface finishes or make-up cosmetics. The color repeatability of products requires precise formulation and detailed measurements - including control measurements, at the stage of receiving the delivery of raw materials and at the production stage. Since color perception is subjective, special color measuring instruments are used to control the quality of finished cosmetics, which ensure repeatable results, not limited by human perception. For this purpose, colorimeters are used, among others. Key words: colorimetry, color cosmetics, make up cosmetics, cosmetic pigments |
