This image shows positions of colloidal particles in a sample where a colloidal crystal is adjacent to a colloidal liquid. Particles that appear to be in a crystalline environment are blue; those in a liquid-like region are yellow or red. Particles immediately at the interface are either light blue or yellow, depending on which side of the interface they are on. The transition region from crystalline to liquid is fairly narrow. The picture is a computer rendering from experimental data.
