自然界中颜色主要通过两种途径产生，色素与光学效应。而其中光学效应包含干涉效应，如光学多层膜;衍射效应，如光栅;光子晶体的光子带隙效应，如孔雀的羽毛。孔雀羽毛绚丽多彩的颜色变化就是由其中光子晶体特殊结构对光的选择性反射生成。
孔雀灯是运用光学色彩结构在家居领域中的一次大胆尝试。
Colors in nature are produced in two ways, pigmentation and optical effects. Optical effects include interference effects such as multilayer optical films; diffraction effects such as gratings; photonic crystals such as peacock feathers. The multicoloured color of peacock feathers is produced by the selective reflection of light by photonic crystals.
Peahen lamps are a bold attempt to use optical color structures in the furniture field.
