Key words:
vocal folds, color, physics, white, larynx.

Objective: The aim of the study was to prove that the natural color of the vocal folds is pink, and not white as seen on laryngoscopy. Methods: The authors performed a revision of textbooks of Physics to analyze the changes of color, based in the physical principles of light, reflection, specular reflection, refraction, conductivity, chromatic aberrations, color saturation and brightness. They also reviewed the descriptions of the color of the vocal folds in more than three hundred textbooks of ENT. Conclusions: The authors conclude that the textbook descriptions of the vocal folds as white are incorrect.
