Thinking it was early 80's an incredible dog would go out with me to the wilderness in the afternoon. Sometimes we went far and came back in the dark. She was a fawn color so the contrast of her fur was good against the green of that countryside. I asked her to walk slow enough for me to follow close behind, me using the amber Photon occasionally if I saw her negotiating some tricky ground. Surprising how long those little coin batteries would last when used intermittently.
Back in those days, Radio Shack had various LED colors one could play with and make strings with a soldering iron, but never did buy a red Photon. They were expensive back then as well.
Thinking it was the magazine "Popular Science" that reported LED developers created a blue emitter. That was fantastic news. I hounded two mom and pop electronic stores in Albuquerque for the new color and finally the blue LED's showed up. Using wire nuts and just twisting the legs of the LED's, made a 12V nightlight using red, orange, green, blue.
Then the white emitters came on the scene. As soon as REI first stocked them, one was attached to my belt loop. Back then
EDC was not known as an acronym for everyday carry.
Used the same technique to make interior lighting with white, bare emitters, using surplus amber LED's to get the voltage right for the off grid 12 Volt solar setup.

Cyan used very rarely but appreciated. Walking a forest trail at night that would briefly go within sight of an active residence, it was so nice to pull out a covert nose Cyan Photon and point it almost straight down where one is just about to walk. Being mindful of wind drift, neither humans or their dogs would be aware of our passing. Just want to quietly pass, letting them enjoy the evening as well.
