We first analyze how color and transparency are perceived. Drawing on principles of light scattering investigated in Part I, we suggest simple rules and procedures in a diagnostic form for visually observing fluid surfactant systems to estimate sizes of dispersed particles. Rules and procedures are organized into a guide, the use of which we illustrate by observing certain important surfactant systems. We conclude that it is possible to estimate particle sizes in the Rayleigh, Rayleigh‐Debye‐Gans, and Mie scattering regimes from such observations alone.
