"LED technology has been around for a little more than 40 years, but the
standard joke in photonics circles was that you could get an LED in any
color you wanted, as long as it was red. Only in recent years have
researchers developed ways to create a range of colors by using
materials such as indium, arsenic, gallium nitride and other
semiconducting solids that glow when zapped with electricity."
... even a red LED is green ...
