Per the title, what LED colour is in fashion for hifi right now? Is it still blue, or has orange taken over? I am about to button up a project and need to pick a power LED, but don't want to regret my decision when somebody posts something nicer in a subforum Gallery this weekend 😀
If there are tubes around, amber. You use a dual color LED with a shunt for a color selector.
A deep HeNe red has always been my favourite. Or a pure green. I doubt any of those are in vogue, though. 🙂

Thanks for all the ideas. I jogged my thinking and made me realize I already have red/blue dual colour LEDs perfect for this specific project.
How about a preference for LED colour behind a smoked lens?

I like the idea of a multi-color (RGB) LED. How about a speaker protection circuit? When the Amp is off (or on stand-by), have it blue. During start-up and the speaker-on delay, have it blinking red. Upon successful start-up and speakers being connected, have it turn green. 😎 If the speaker protection is tripped, the LED returns to blinking red.
Just my two one-hundredths of a dollar.

Plain old red for me, I don't care what is trendy. red is like the timeless little black dress that all women own.
Besides, anyone can mount an LED, but it takes a real man to have a light up logo for the job.

While I agree red is pleasing and timeless, I don't like using it for on/off because so many modern commercial devices use red as the "off" or "sleep" colour, and some other colour for "on". Our 2 big TVs use red for "off" and nothing else for "on", because of course the screen itself is lit.

Orange or white.
Years ago I bought a lot of purple LEDs that slowly turned pink. I called it the "Burn-in Indicator." 😉

How about Multi-color led and make it user selectable like those new car interior lighting

White is the least contraversial option to my mind - you could make interchangable coloured filters if you wanted customization. However red is the most restful to the eye, especially at night. Amber is good for this too and often overlooked as an LED colour.
The most important aesthetic to me is that all the LEDs are the same colour (excluding warning lights), and red is common enough that its possible to have separates that match.
In high ambient light green is the most visible as that's the peak of human sensitivity, which
is why 555nm green used in the standard definition of the lumen and lux units. However green always reminds me of old green-screen computer monitors from the 80's!

That means it’s time to add more chlorine/bromine. That should turn it back to purple.
For myself, the "blues" do it for me...there seemingly exists some blues that I firmly believe extend into the ultraviolet range...they have that peculiar color, differing from others.

That wouldn't work so well for LEDs. Even the white ones tend to emit discrete peaks of low, mid, and high wavelengths that, when combined, are perceived as white(-ish). If you were to put, say, a yellow filter in front of a "white" LED, you wouldn't get much yellow light through.
One of my former coworkers at National had a side-business building LED inserts for classic car taillights. Some of them have a blue dot in the middle of the lens. His unique selling proposition was LED inserts that could make that blue dot light up (as it would with an incandescent bulb). Basically, he had a blue LED in the right spot.

Junk electronics like Bluetooth loudspeakers - the nastier the product, the brighter he blue LED.
Blue and white LEDs produce a lot of extreme blue, even near UV light that have caused the anti-blue optical lens coating industry
