Shade selection is a crucial clinical step during prosthetic treatment. Nevertheless, because it is based on subjective criteria, very often the esthetic result is compromised due to inadequate color reproduction. In order to explore this complicated problem, this paper attempts to analyse it as scientifically as possible. Initially, the physical phenomenon of "Color" is analysed. Color depends upon the light source, the object and the observer. Metamerism is the fatal enemy in shade matching. Shade selection through the use of shade guides is inadequate due to lack of standardization. Therefore the possibilities of improved application of the available materials are thoroughly explored for both simple and more complicated cases. Best results can be achieved by segmental color selection (separately for dentin and enamel).
选色是修复治疗过程中的一个关键临床步骤。然而，由于它基于主观标准，常常因颜色再现不足而导致美学效果受损。为了探究这个复杂的问题，本文试图尽可能科学地对其进行分析。首先，分析“颜色”的物理现象。颜色取决于光源、物体和观察者。同色异谱现象是选色匹配中的致命敌人。由于缺乏标准化，使用比色板进行选色并不充分。因此，针对简单和复杂病例，都对现有材料改进应用的可能性进行了深入探究。通过分段选色（分别针对牙本质和牙釉质）可取得最佳效果。
