隨著顯示器、固態照明技術的迅速發展，對顏色豐富性與真實性的要求越來越高，使得色彩量測與評價的重要性日益增加。另外利用光交互干涉的方式所產生的色彩，其色彩的品質極佳，而光學薄膜即為實現光干涉產生色彩的重要技術。所以本文除了介紹色彩科學中幾個常見的表色系統、色彩的計算方式、光源及色彩量測的方法，更藉由周遭常見的光學薄膜應用為例，搭配色彩科學的方法深入探討、分析光學薄膜在色彩顯示上的應用。

Color plays as an important role in our daily life since there was human culture. As the rapid growth of display and solid state lighting industry, the requirement for the variety and fidelity of color performance is much more than ever before. Hence the importance of color measurement and evaluation method increases day by day. The quality
of color produced from interference of lights is remarkable, and the optical thin film which exists around our life is the principal technology to achieve this task. It has already been demonstrated in animal, plant, and mineral. At first, color system, photometry, light source, color temperature, color rendering index and color measurement will be introduced in this article. And then, several applications of optical thin film in nature and man-made will be cited as instances to discuss and analyze by using the methodology of color science.
