Light: Science & Applications

Existing colour systems, such as RGB and CYMK, are all text-based and require a large range of values to represent different colours, making them difficult to compute and time-consuming to convert. Recently, researchers from City University of Hong Kong (CityU) made a breakthrough by inventing an innovative colour system, called “C235”, based on prime numbers, enabling efficient encoding and effective colour compression. It can unify existing colour systems and has the potential to be applied in various applications, like designing an energy-saving LCD system and colourizing DNA codons.

A recent study, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has introduced a flexible and transparent solar cell, using silicon microwire composites.
