Why would the Blue LED be worth billions?

Glacier :

what about black LEDs

Jerry :

Blue LEDs were invented much later than red and green ones. That is why early digital clocks used red displays and early computer monitors were monochrome green. Once scientists finally developed the blue LED, combining Red, Green, and Blue (RGB) made modern full-color displays possible. Without the blue LED, modern color screens wouldn't exist.

I remember when a single red LED was about 15pence, but a blue one was nearer £5. (High street prices, online shopping didn't exist in the 80s!)
