A new coloring material based on the Morpho butterfly's intelligent nanostructure was developed with its processes. The biggest characteristic of the Morpho- color is the single color in wide viewing angle (not rainbow color) despite its principle of the interference effect, which looks contradict with physics. The key of this peculiar coloration is fine combination of order and disorder in nanoscale. After the proof of this principle by reproducing the Morpho-color (before this project), the large scale and fast fabrication process was developed in this project, which has long been a serious barrier to the application. Furthermore, the optical role the nano-randomness was elucidated by FDTD analysis and the design of the randomness was enabled, which was impossible so far.

基于Morpho蝴蝶的智能纳米结构，开发了一种新的着色材料。Morpho-color的最大特点是宽视角下的单色（不是彩虹色），尽管它的原理是干涉效应，这看起来与物理学相矛盾。这种特殊颜色的关键是纳米尺度上有序与无序的精细结合。在通过复制Morpho-color（在该项目之前）证明了这一原理之后，该项目开发了大规模和快速的制造工艺，这长期以来一直是应用的严重障碍。通过FDTD分析，阐明了纳米随机性的光学作用，实现了迄今为止不可能实现的随机性设计。
