Funny, when I got tired of trying to find a nice desktop background I just started using a solid color of muted blue or green. I never read about this specific usage of colors before but I bet I saw something somewhere that clued me in on this color.

#142The 68 Ford Thunderbird (w/ suicide doors.) Mustangs also came in this color.

Reminding me that early Windows versions used to have this colour as the default desktop colour -- and I remember seeing similar tones on Mac and Unix desktops in the 90s.

IDK if you've noticed but we are all lighting our house with bulbs that use 1/10th the amount of electricity as incandescents did. I like the color spectrum of a real lightbulb better, too, but not enough to pay 10x in power. I make up for it by using all kinds of random bulbs all over the place so that the aggregate light in the room fills more of the spectrum than if I coordinated them all to be the same.
The problem is we went from a market that consisted of cheapo/good bulbs at various brightness levels to a market where Walmart and Home Depot have like 60 linear feet of bulbs. There’s no standards and people are clueless and confused. There are awesome LEDs, but more often you see have harsh, terrible light.
Cluing in is really easy. Look for "CRI ≥ 90", or at least "full-spectrum" for the lamps that are easy on the eyes. Pick 2700K for softly lit spaces, 4000-4500K for brightly lit spaces.

#145Wait, what? Ending the war in Japan was "indefensible"?

#146> There’s a lot of U.S. history that’s awful and indefensible Sure. But this is not one those things.
I'm with you.

#147I went to an old engineering school for grad school, all the older buildings had this color scheme.

The monochromatic light emitted from sodium lamps is also close to the peak sensitivity of the human eye. Colours are not distinguishable, but contrast is much enhanced compared to “cooler” light sources. *edit: but it’s the overwhelmingly larger lifespan (20-30k hrs) that led to the wide adoption as streetlights. And I guess, the same is true for the change to led today, because of less power consumption.
It's not especially close to the peak sensitivity of the human eye (in either bright or dim conditions), but that's entirely okay. The goal should be to not affect people's level of dark adaptation. If you use shorter ("bluer") wavelengths, as happens with white LEDs which consist of a blue LED + phosphor, it causes people's eyes to become bright adapted and effective night vision is ruined, causing people to have mu…

Wouldn't that be red light? But night scenes illuminated in red light have the side effect of looking nightmarish..

If I could run different lighting after sunset, I'd run something high-CRI in your range during the day and a low-CRI 3000 after sunset. As it is, I compromise.
There are LED lamps which have a "warm dim" feature so that the appear oranger as you reduce the brightness.
Thanks, that's great to know! However, I also had to remove the high-CRI lights from some lamps because I found that they disturb my sleep if I have them on in the hours before bedtime.
I live in a 240-volt country, though, and I've never seen a dimmer switch here.

That's not necessarily a downside for traffic safety, though. Though I imagine someone must have studied the effects of various wavelengths on drivers...
