In this study, Nematic Discotic (ND)—Nematic Biaxial (NB)—Nematic Calamitic (NC) phase sequences are investigated for some surfactant-based lyotropic mixtures. From the microscopic analysis point of view, the nematic phases, especially NB one, are characterized by a methodology we developed to create a resultant image via composition of many microscopic textures (images). The resultant image permits recognizing the NB phase bordered by two verticals imaginary lines contrasting two distinct colors. To consolidate our methodology, we simulated the interference colors chart of the samples for the first time via birefringence measurements performed by laser conoscopy technique. The simulated and experimental results are in good accordance.
