Color fitting in prosthodontic and restorative therapy is a really considerable task since it affects the esthetic outcome of dental restorations. Both color communication and evaluation are crucial to making a lifelike realistic restoration. Shade is an outstanding type of psychophysical sensation in the eye brought on by visible light.1 Present techniques for selecting shades can be affected by the objective and subjective variables that can greatly influence the quality of the final prosthesis. These factors include light source, surrounding environment, and the clinicians'/technicians' understanding of colour. The lighting source and environment can easily be changed by using color-corrected lights and by employing neutral, neutral background colours during shade selection. Human factors are more difficult to equilibrium for, as colour perception differs due to age, eye fatigue, and neural-color receptors in the eye.2 To at least partly offset these factors, outstanding communication must exist between the dentist and laboratory technician. There are two color matching methods in dentistry: visual (conventional) and instrumental. Visual shade determination, when comparing to patientвЂ™s tooth with color standard, is the most frequently applied method in clinical dentistry.3 However, visual shade matching is unreliable, inconsistent and considered highly subjective. This is the result of multiple factors such as individualвЂ™s physiological and psychological responses to radiant energy stimulation, aging,fatigue, emotions, lighting conditions, object and illumination position, previous eye exposure and metamerism.4,5 Furthermore, human eye can detect very small differences in color, the range of available shades in the shade guides is inadequate and i.. .
