Abstract The possibility to obtain a desired color of the product and to ensure its repeatability in the production process is highly desired in many industries such as printing, automobile, dyeing, textile, cosmetics or plastics industry. So far, most companies have traditionally used the "manual" method, relying on intuition and experience of a colorist. However, the manual preparation of multiple samples and their correction can be very time consuming and expensive. The computer technology has allowed the development of software to support the process of matching colors. Nowadays, formulation of colors is done with appropriate equipment (colorimeters, spectrophotometers, computers) and dedicated software. Computer-aided formulation is much faster and cheaper than manual formulation, because fewer corrective iterations have to be carried out, to achieve the desired result. Moreover, the colors are analyzed with regard to the metamerism, and the best recipe can be chosen, according to the specific criteria (price, quantity, availability). Optimaization problem of color formulation can be solved in many diferent ways. Authors decided to apply genetic algorithms in this domain.

Alexander Parkes found the earliest plastic in 1850. American scientist John Wesley Hyatt achieved the first patent of plastic (1970) and inaugurated the first plastics industry (1873) with his brother in the world. From then on, plastics industry all over the world have experienced about 150 years development. Based on the learning from overseas industries, China gradually constructed and cultivated himself plastics industry system that is full of Chinese characteristics. The amount of plastics production, plastics products and plastics machine production as well as plastics consumption in China increased quickly. The value of plastics import and export trade rose year by year. Nowadays, China reaches an advanced level in the world no matter plastics machine production, plastic goods production, plastics consumption, or outlet of plastics machines and products. Plastic industry has be one of the important light manufacturing pillar industries in society and economics development of China.
