Color superconductivity

Color superconductivity is when materials (like metals and alloys) become superconducting at temperatures that are very cold. This means electricity can flow through them without any resistance or loss of energy. What makes it interesting is that when these materials become superconducting, they also form what are called "color charges". These color charges are like the electrical charges in regular electricity, but they come in three different colors: Red, Green, and Blue. This special type of color charge helps the electricity to flow in a really neat way.
