Design and Optimization of Moldable Microstructures for Structural Color Generation
The use of structural color, common in nature, has been slow to catch on in manufacturing. Recent work has identified many of the structural features that lead to the advanced structural colors seen in nature, and some have even been successfully recreated. However most of these features are …

Materializing Light: Real-time, Handheld Fabrication of Programmable Structural Color
Structural color is nature’s programmable color palette. While pigments and dyes absorb light to produce color, structural color uses nanoscale, light-reflecting structures to appear iridescently colored. We present MorphoChrome, an optical device for real-time, handheld, programmable structural …
