Factors affecting the choice of producing wavelengths for recording true-color holograms are examined. It is argued that the choice of wavelengths is largely independent of the method used for recording and, in fact, largely independent of holography. It is shown that a large area of the CIE chart need not be covered and that, in fact, choosing wavelengths that cover a large area can have deleterious effects. A set of three wavelengths is proposed which, in principle, can produce true-color holograms of excellent quality. A convenient method of obtaining three acceptable wavelengths is discussed.
