Pigments can be both organic and inorganic. The type of pigment impacts its properties, such as brightness, longevity, and opacity.
Organic Pigments
- Definition: Organic pigments contain carbon atoms and are often derived from coal tars and other petrochemicals. Britannica
- Characteristics: Typically brighter, purer colors with high tinting strength. They are often lighter in weight. Daniel Smith
- Examples: Many synthetic organic pigments are used today. Historically, organic pigments were sourced from natural materials.
Inorganic Pigments
- Definition: Inorganic pigments are made from minerals and salts, often based on oxides, sulfates, sulfides, and carbonates. Meghmani Global
- Characteristics: Generally more muted and earthy tones. They are known for their brightness and lasting power, often exceeding that of organic pigments. [Reference 1] They are usually opaque, unlike organic pigments which tend to be more transparent. Brenntag They are often dry-ground minerals containing metals. Packaging School
- Examples: Cadmiums, Cobalts, and Earth colors are examples of inorganic pigments. EmptyEasel
