Structural colour is an important concept in nature and materials science. Studying it helps us understand how colour can be created without pigments, using physical structures that interact with light. This has implications for sustainability, as structural colour does not fade and avoids the use of harmful chemicals. The slide deck introduces these ideas through familiar animal examples and shows how physical computing, using a micro:bit, can be used to explore light, colour, and reflection in a practical way.
