Common LED colors include amber, red, green, and blue. There is actually no such thing as a âwhiteâ LED. To get white light, the kind we use for lighting our homes and offices, different color LEDs are mixed or covered with a phosphor material that converts the color of the light. The phosphor is the yellow material you can see on some LED products.
