I distinctively remember buying my first blue LED in what must have been the mid-90s. I simply walked into an electronic parts store and bought a single spare LED. I don't think I had ever seen a blue LED in action before, it was completely new to me, so I was very curious.
It was of the very common standard shape and size LEDs were during that time, and its case was colorless but cloudy, not clear. A good thing, because that meant the LED would emit its light along the entire casing, not just straight forward, making it much easier to look at. It also wasn't much brighter than other LEDs, that came later.
When I applied power and saw it shining in that beautiful blue color, I was positively amazed. This was so much cooler and so much more beautiful than the red, green, and yellow LEDs I had been using before. I distinctively remember just leaving it attached to power, sitting on my desk, just for something nice to look at.
