Use real pure black color in web pages instead of dark gray color to save battery in dark mode without the need of heavy extension about thorium HOT 6 OPEN

first of all... you do understand that "black saves battery" only applies to oled screens, right? you say your computer is old, and the odds of an old noisy computer having an oled screen are pretty slim, considering that they are still a luxury even on high end laptops released these days.
second, amoled black doesn't save any more battery than dark gray (https://www.xda-developers.com/amoled-black-vs-gray-dark-mode/), so what you are asking wouldn't help achieve your goal even if your laptop did have an oled screen

ciancy, do you understand that the recent scientific study that I posted saying dark reader is one of the extensions in the world that consumes the most CPU power? so in any case a native black mode of Thorium will cost less resources than the dark reader extension, dark reader is good but I feel the connection can become a little slow and I feel the fans running, and I like black mode...if you say right, surprising that black mode does not save more energy, it says black mode means the pixels on the screen are off and inactive because there is black mode.... This is a fascinating subject, more testing and comparisons are needed...

@Ciancy28 first of all , you do understand based on your own article : "so it should output 0.3 nits. 4mW/nit × 0.3 nits = 1.2mW, so dark gray should only consume 1.2mW more than pure black.", "So, theoretically, dark gray consumes a negligible amount of additional power compared to using black."

we don't all live in rich USA, we don't all use renewable energies and I live in a country where the price of electricity is the highest in the world, 0.3% energy savings via black mode is a saving anyway, it doesn't matter, it's not much, and then I don't care about the amoled screen, my computer is asus i3 2017, so my screen is either an ips or lcd screen... what interests me is that is a study of black mode on this type of screen

from thorium.

it says "OLED saves power if pixels are turned off with true black screens. IPS actually uses the least power with a white screen when the color layer doesn't have to work. Not much of a difference overall though, i would still use dark mode to strain my eyes less at night"

but i think black mode can reduce blue light =better sleep

That graph doesn't include the browser's native dark mode, so there's no data proving that "a native black mode of thorium will cost less resources", and the "dark reader is one of the extensions that consumes the most cpu power" part is also not true, looking at the graph, it's actually the LEAST cpu power consuming extension.

surprising that black mode does not save more energy, it says black mode means the pixels on the screen are off and inactive because there is black mode.... This is a fascinating subject, more testing and comparisons are needed...

It's not surprising and no further comparisons are needed if you understand how oled screens work... a gray pixel is barely lit, it's barely emitting any light, so there's no reason to think it would use up a significant amount of power compared to a fully turned off one, especially considering that power consumption isn't linear (a 1000 nit backlight/oled pixel will use more than double the power of a 500 nit one).

it definitely matters that it's not much, and this doesn't change no matter where you live or how much electricity costs, also you are missing a lot of context of that experiment
It's 0.3% on a a small phone, that's being run by a very efficient arm based SoC, and showing a static image (so probably close to 0% cpu usage), on a laptop with an x86 cpu doing actual work (or even at idle), you would be looking at way less savings.
btw italy isn't exactly located in the usa.

not really, again, if dark screens barely use any more power compared to black ones, the same should go for the amount of blue light emitted.

dark reader has the least CPU consumption among the energy-intensive extensions, compared to other extensions, I do not criticize this extension which does a good job, the dynamic mode is demanding in energy, and I tested the browser myself with dark mode enabled in chrome flags and I activated full black color in Firefox and I compared with dark reader extension activated and I feel the difference, the fan remains silent with the native black mode of browsers....I read articles saying black mode can reduce blue light
