MIT boffins create device that 'paints' iridescent structural color in real time

From adaptive wearables to light-based signaling ideas, researchers are exploring what comes next The feathers of a hummingbird, the wings of a butterfly, and the sparkle of an opal are all examples of nature's ability to produce structural, iridescent colors that typically require lab-grade materials and techniques to replicate. An MIT team says it has found a way to make that process far more accessible.…
