Värvpigmentide

Värvpigmentide, also known as color pigments, are substances that impart color to other materials when mixed with them. They are insoluble in the medium they color and work by selectively absorbing and reflecting certain wavelengths of light. This selective absorption and reflection is what we perceive as color. Pigments can be organic, derived from living organisms or synthetic organic compounds, or inorganic, typically derived from minerals or synthesized inorganic compounds.

Inorganic pigments are often more stable and durable than organic pigments. Examples include titanium dioxide (white), iron oxides (red, yellow, brown, black), and cadmium pigments (bright reds and yellows). Organic pigments, while sometimes less stable, can offer a wider range of brilliant and intense colors. Examples include phthalocyanine pigments (blues and greens) and azo pigments (yellows, oranges, and reds).

The choice of pigment depends on the intended application. Factors such as lightfastness, chemical resistance, opacity, particle size, and cost all play a role. Pigments are used in a vast array of products, including paints, inks, plastics, cosmetics, textiles, and construction materials. Their ability to provide color and visual appeal makes them essential components in modern manufacturing and design. The properties of a pigment are determined by its chemical composition and physical structure.
