This is really specifically wild for me to stumble onto here. Let me explain. In the early 90s, a few of us in the clubs were into the whole "cyberpunk" movement that was pretty new back then.
Some club denizens went as far as to create electronic apparel, with an LED or two, and one guy even made a skin temp sensor and connected it to an LED bar graph, so the more he exerted himself the higher his temp would show on his arm.
Anyway.... everyone has either red or green or yellow. I wanted a blue. Couldn't find one.
Internet was pretty limited back then, so a lot of shopping in parts stores, catalogs. Etc....
We finally found a supplier in China that manufactured blue LEDs, but we'd have to buy like 250,000. Somehow this dude gets a hold of exactly 5 of them. He worked a deal with a store who ordered the he quantity and let him buy 5.
Craziest thing, the turn on voltage for the ones We used was 6V. So, strapping 4 AAA batteries somewhere on you would give you 6V.
These blue LEDs from China needed 5V.
Took a while, but we figured out that rechargeable batteries output 1.25V, so we used 4 of those to achieve the 5V turn on voltage. The whole thing took about a year while we figured it out.
Haven't thought about it in 30 years. Then I run across this random article telling me exactly why what I tried to do 30 years ago was so difficult.

It's been moving towards this since the 80s. They're some real big brains there.

I'm pretty sure that's been the plan in play for a while. The real trick was convincing over half the population that they wanted it.

When Thriller was released (1984 1982), he was like, the most famous pop star on the planet for about a year. Everyone trying to Moonwalk all the time.
