Abstract
Natural and synthetic pigments have both advantages and disadvantages. It is usually easier and cheaper to isolate the pigment from plants than to synthesize. At the same time, synthetic dyes are more resistant to various environmental factors, which allows to use them widely. The paper examines the influence of high temperature and pH on colour and stability of anthocyanins and phthalocyanine, as well as the benefits of their use.
