My favorite thing about widely-available blue LEDs was the effect on TV scifi.
Watch the Star Trek shows made in the 1980s and 1990s and the tricorders, alien gadgets, and other props were always twinkling with red, yellow, and green LEDs to look futuristic. A generation later and every single hand prop on 2000s Doctor Who, Torchwood, etc. glowed and twinkled blue because the LEDs had just become cheap enough for prop makers, but weren’t yet widespread in day-to-day life so the viewers were seeing something strange and unusual.
Now every color of LED imaginable is just common and whatever, but for a good stretch of time glowy blue became the standard “scifi” color just because that particular tech happened to turn up at that particular time.
They’re still rgb plus maybe yw using colour mixing, so depending on the quality, tuning, physics and our perceptionof light, not all colours are as nice or bright.
Oh I was making a joke cause it sucks at purple. Which is red and blue combined generally. But that’s not really how the RGB color cycle works as far as I understand in some extremely cursory Wikipedia reading lol
IIRC, it has something to do with the fact that purple sort of doesn’t actually exist. As I understand, purple is basically your brain going “idk wtf it is but it’s not green”
More specifically, it’s because purple fires your red and blue cones, but not the green one. Normally, as green is between red and blue, anything that would trigger those two also would trigger green. So when it doesn’t, that’s when your brain goes “well I guess it’s not green???”
I’m not sure that LEDs were the thing that kicked off the trend. They made it easier to implement, but even in the 80s and 90s, you had things like Tron that might have kicked off the futuristic look with neon lines/tubes.

Purple still seems to be a tough one for most rgb devices I’ve used lol

Yeah. I just think being RgB it would be good at purple 😂 One of those situations where the name was probably not created based on logic lol
It’s called RGB because there’s a red, green, and blue diode. Not sure how that’s not a logical name.

lol my favorite color would be a weird one. 😂
Right there with you.
