Why LED lights can change color: Color can be changed by changing the current. Light-emitting diodes can be easily chemically modified to adjust the band structure and band gap of materials to achieve red, yellow, green, blue, and orange multi-color light emission. For example, an LED that is red at low currents can turn orange, yellow, and finally green as the current increases. The core of...
