szénanyag

Színanyag is a Hungarian term that translates to "pigment" in English. It refers to a material that has the property of changing the color of reflected or transmitted light as the result of selective absorption of light wavelengths. Pigments are typically insoluble in the medium they are applied to and are used to impart color to paints, inks, plastics, cosmetics, and other materials.

Unlike dyes, which dissolve in their medium, pigments are solid particles that are dispersed. This insolubility is a key characteristic that distinguishes them from dyes. The color of a pigment is determined by its chemical composition and crystal structure, which influence how it interacts with light. Different pigments absorb and reflect different wavelengths of light, resulting in the perception of various colors.

Historically, pigments were derived from natural sources, including minerals, plants, and animals. For example, ochre, a natural clay earth pigment, has been used for thousands of years. Over time, synthetic pigments were developed, offering a wider range of colors, greater stability, and often lower cost. The production and application of pigments are fundamental to many industries, including art, manufacturing, and design, providing the visual appeal and color identification for countless products.
