Pigment versus Melanin
Pigment is a broad term for any substance that gives color to materials, while melanin is a specific type of natural biological pigment found in humans and other living things. [1]
- General definition: A pigment is any chemical compound that reflects certain wavelengths of visible light and absorbs others, creating a specific color. [1]
- Wide variety: Pigments can be natural or artificial, and they exist across plants, animals, minerals, and manufactured goods (such as paints and inks).
Multiple roles: Beyond coloration, pigments can provide camouflage, thermal regulation, or protection against light in different organisms.
- Specific biological type: Melanin is a specific natural pigment produced by specialized cells called melanocytes. [1]
- Location in humans: It determines the color of your skin, hair, and eyes. [1]
- Protection: Melanin absorbs harmful ultraviolet (UV) radiation from the sun to protect your cellular DNA from damage. [1, 2]
- Main types:
- Eumelanin: Produces brown and black shades.
- Pheomelanin: Produces red and yellow shades. [1, 2]
- Scope: Pigment is the general category; melanin is a single, specific item inside that category.
- Origin: Pigments include man-made dyes, plant compounds (like chlorophyll), and animal compounds. Melanin is strictly a natural biological polymer made by living organisms. [1, 2]
