What 3 factor affect the rate at which pigment migrate?

The rate at which pigment migrates is influenced by several factors, including the size and charge of the pigment molecules, the viscosity of the medium they are traveling through, and the method of migration (e.g., capillary action, diffusion, or electrophoresis). Smaller, charged pigments typically migrate more quickly than larger, neutral ones. Additionally, a less viscous medium allows for faster movement, while increased temperature can enhance the kinetic energy of the molecules, further accelerating migration.
