pigment meaning
ENWPigment
- A pigment is a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption.
- Many materials selectively absorb certain wavelengths of light. Materials that humans have chosen and developed for use as pigments usually have special properties that make them ideal for coloring other materials.
