Multi-Primary Color Display Emerges as Next-Gen Color Reproduction Technology

enough studies and randomized control trials have been conducted, it is conclusively shown that blue light emitted from household devices does not interact meaningfully with sleep. metareview CRD420251034611 "non-significant reduction in sleep onset latency" means blue light has been conclusively observed to not delay sleep - it doesn't mean that blue light has not yet been observed to delay sleep, we instead know conclusively that it does not. even better, a registered trial one: https://clinicaltrials.gov/study/NCT01855126 - RCT where shining a bunch of blue light on old people's eyeballs didn't help them stay awake longer (going to bed too early is actually a more common clinical issue than staying up too late). well if it can't keep people awake, it doesn't keep them awake.

it's a great interview question though. "does blue light from screens cause sleep delay?" it doesn't. why do so many people think it does? why suffer with a piss colored screen?

And to a certain extent, she was right, but it was not "the blue light" per se that was damaging my psyche. Rather, it was the stuff within the light that was getting me agitated and angry. It was the disputes on Wikipedia, the social media arguments, the ragebait I found everywhere, the F.U.D. leading to my paranoia and rebellion and loss of trust.

It's like people who say "5G is harmful to our brains" -- well, yes, because whatever is being transmitted over that 5G is harmful, like porn or social media -- not the mere frequencies themselves!

However, in CRT displays, the color of the light emitted by the red phosphor was rather impure, far from a saturated red.

This limitation has been inherited by the sRGB color space, and because of this, the main defect of sRGB is that it cannot reproduce a lot of colors in the yellow-orange-red-purple corner.

This is very noticeable, because there are a lot of natural objects with such colors, e.g. flowers, fruits, birds, insects, clothes, whose colors appear washed out in sRGB, but they look much better on displays with greater gamut, like P3-D65 (Display P3) which is available in better monitors.

While the colors in the cyan corner cannot be reproduced well even with a laser projector, that is usually less objectionable than the poor reproduction of yellow to red colors by sRGB monitors, because interesting cyan objects are more rarely encountered (though they exist, e.g. certain gems, lichens, algae, insects, lizards and fish, certain clothes, frequently the littoral sea).

I believe the leading theory is that red light is given off by a variety of fruits when ripe so arboreal ancestors with that mutation could much more easily locate food. To most mammals red ripe apples and green unripe ones are all just shades of yellow so the mutation would have been like a superpower: the equivalent of eagle-eyed vision.
