The two-toned color is normal. It is a result of the extraction process of the beta carotene from the algae, D. salina. Beta carotene is extracted from the algae with the naturally occurring solid particles which carry the beta carotene. When encapsulated, the solid particles may migrate over time in the capsule. These solid particles refract light in such a way as to show a milky iridescence like that of an opal. The term used for this quality is "opalescence". Thus, this opalescence is a natural property of the algae from which the beta carotene is extracted.
