Unlike certain materials emitting light through processes such as fluorescence and luminescence, high-quality pigments change the transmission or reflection of light’s coloring through the process of absorbing selected wavelengths of light. This process allows the human eye to see the remaining wavelengths as a distinctive color.
Pigments are made up of small particles of insoluble materials. Organic pigments — which contain carbon — have been in use for thousands of years and are made from natural materials. Today, however, most organic pigments are synthetic organic pigments made from petrochemical derivatives.
It is essential to understand the difference between pigments and dyes. The majority of pigments are insoluble and most often ground into the form of a fine powder. As a result, the process of giving a distinctive color to materials such as paints requires the mixing of a pigment in powder form with a liquid vehicle — or binder — that then suspends the given pigment before it’s applied and adhered.
Dyes, on the other hand, are either liquids or soluble materials suspended in liquids. In contrast to paints, dyes add color by staining the materials they are applied to.

Types of Pigments
What follows is a closer look at some of the most popular pigment types and classifications.
- Organic Pigments: High-quality organic pigments provide long-term color retention to materials such as plastics, inks, paints, fabrics, food, and cosmetics.
- Mica Pigments: Mica pigments are the result of mixing the mineral mica with another pigment or colorant. This process produces shimmering, glassy, color-shaded micas that produce a shine effect in popular cosmetics and makeups.
- Pearl Pigments: Pearl pigments, sometimes known as pearlescent pigments, impart a specific type of interaction with light known as the process of multiple reflection that produces a highly transparent shine similar to the surface of a highly polished pearl.
Industrial Considerations When Using Pigments
From the metallic shine on the hull of a motorboat to the pearl-like luster on the body of an electric guitar, pigments bring vivid colors and particular finishes to all sorts of products in our world today.
