Interference pigments, also known as pearlescent pigments, consist of multiple layers, centered on a core material, usually mica. These layers typically include a base layer of mica, one or several layers of metal oxides like titanium dioxide or iron oxide, and optionally a top coating for additional effects or protection. The exact number of layers varies, but generally ranges from 3 to 7, depending on the desired color, opacity, and pearlescent effect. By fine-tuning the thickness and composition of these layers, manufacturers can produce pigments that reflect and refract light in unique ways, creating vivid colors and iridescent effects used in automotive paints, cosmetics, and coatings.

[Flavonoids, a diverse group of phytonutrients present in many plants, are responsible for the vivid colors in fruits, vegetables, and flowers. These compounds undergo biosynthesis in plants, involving several biochemical steps that bring about their diverse pigmentation. In essence, flavonoids absorb certain wavelengths of light and reflect others, a process that dictates the color we perceive. The specific coloration depends on the flavonoid’s structure, such as the number of hydroxyl groups attached and its overall arrangement. For instance, anthocyanins, a type of flavonoid, can appear red, purple, or blue, depending on the pH of the plant cell sap. This versatile pigmentation plays a crucial role in plant life, attracting pollinators and protecting against UV rays. Additionally, the antioxidant properties of flavonoids contribute significantly to the health benefits of consuming a diet rich in fruits and vegetables.]
