The Colorful World of Science

Color

• Color is a form of electromagnetic radiation that is visible to the human eye, with wavelengths between approximately 380-780 nanometers
• Colors can be described in terms of their hue, saturation, and brightness

Dyes

• Dyes are substances that impart color to a material or substrate, typically by dissolving in a solvent
• Dyes work by absorbing certain wavelengths of light and reflecting others, creating the appearance of color
• Dyes are typically used to color liquids, such as inks, paints, and textiles

Dyes vs. Pigments

• The key difference between dyes and pigments is their solubility: dyes dissolve in a solvent, while pigments do not
• Pigments are insoluble and remain suspended in a solvent, scattering light to create color
• Dyes are generally used for coloring materials that require a high degree of transparency, such as fabrics and inks, while pigments are used for materials that require opacity, such as paints and coatings
