    White paper and black text is the norm because until relatively recently, it was much more cost effective… This could be done cheaply with modern tech, and should 100% be a thing…

    I’d buy the hell out of dark mode books.

          Its context was that it was a plea from media companies to stop pirating movies/music. Its more “You wouldn’t steal a car, well downloading pirated content is the same”

            I was in college for Computer Science when these ads must have just started because in a Computer Ethics class, I remember the teacher actually using “you wouldn’t download a car, would you” argument.

            I recall answering… “Would the original owner still have their copy? Yes? Then yes, yes I would download a car.” The teacher did not like me.

        Bleaching is to mainly remove tannins, to make the paper white, and to stay white over time. It also makes the paper better able to absorb and retain ink. You don’t need any of those properties if you’re printing in white, because you can’t use absorbent type ink in something like this, it won’t show well. You could dye in lieu of bleaching (and this might be cheaper actually).

        Printing the text is the challenge. The ink has to be on the paper instead of in the paper… The methods required to do that and come up with a quality product have existed for a very long time, but they’d be methods used to create high end things like wedding invitations and greeting cards and not bulk products like books. I believe the first tech that could do this economically at scale was the photocopier (maybe mimeograph?), which basically melts plastic onto the surface, and could apply clear white text onto black paper as easily as black on white.

        I would imagine though, that the tech that could do this in the most economically viable way, would be to ablate the text in with lasers, similar to thermal printing. That would actually reduce the consumables used, maybe even by a lot. likely would overall entail much less hazardous/caustic consumables too… Dark mode printing could possibly be incredibly “green” :)

      I prefer light mode in light environments and dark mode in dark environments. I find it’s easiest on my eyes when the background of the text matches the room ambience. (of course this has to be paired with matching screen brightness)

        Poor contrast is what kills your eyes. You should adapt your screen to your environment.

        Problem is, not many screens can compete with the of light of a sunlit room for daytime viewing. That makes dark (text) on dim (background) on light (environment) very rough. Even for daytime viewing light (text) on dark (background) on light (environment) can feel better.

        But dark (text) on (light) background on light (environment) is excellent if you can accomplish it, since it’s only single step of high contrast because your monitor blends into the environment.

    Books use the color scheme they do because it’s cheaper to print black ink on white paper than white ink on black paper. Digital displays don’t have that limitation.

        Every software needs a “just turn off the pixels that aren’t displaying anything” mode for OLED. Way too many “dark modes” are just dark grey which still keeps the background pixels powered.

          Yes, because full black/white contrast is harsher on the eyes than a dark grey with white or light-grey text. For power/efficiency, black pixels definitely makes sense, but concerning user experience and eye strain, there are many good reasons certain color palettes are used.

            Obviously not every single OLED panel can be tested for this if the manufacturers don’t do it themselves, but a few places tested OLED/AMOLED phones and found slate grey is close enough to full black in power savings. Since then I just choose the most visually pleasing theme as some full black themes are really poorly designed.

          No because the white parts are what will burn in. Black is the off state for OLED. This is also why many apps for Lemmy (and previously reddit) have a dark theme option for OLED devices that uses full black instead of grey so that the pixels not in use are fully off.

            Exactly, and because the rest is off you’ll notice it earlier. It still depends on how long those pixels are on though. The longer they’re on the more they degrade.

            If the whole display is on all of the pixels would degrade eventually, but you’ll notice it less because they all degrade.

              If you have the same pixels on all the time then yes you’d have faster burn in. However, since you’d be looking at different text, this degradation would be spread over the different pixels. Not uniformly, but good enough that it doesn’t matter for practical usage.

        In all seriousness that’s not usable because the ink will have a tendency to bleed and fill the voids that make up the letters.

        It takes more energy, and therefore battery, to draw everything but the letters and words.

          E-ink actually doesn’t as it only uses power when pixels change between black and white and not when it’s displaying a static image. E-ink uses the same amount of power rendering white text on black as black text on white. However, white text is more common since e-ink is specifically meant to imitate printed pages, and assuming it’s not backlit, also doesn’t have nearly as bad eye strain issues when in light mode as a glowing screen does.

          It only has to update the parts where the words changed and it only uses the energy to initially change the screen. It literally uses more energy doing full screen wipes (flashing between black and white three or four times) to avoid ghost images. It would significantly reduce the need for a refresh if it was mostly black.

          Our eyes are more sensitive to variations in lighter colors after all.

        Maybe his eyes are bad. I have astigmatism and especially the combination light text on dark background at low brightness is hard to read for me, because the letters “bleed out” (think like streetlights through a foggy window).

            Maybe astigmatism can have different orientations, it’s a wrongly shaped lense, after all. And there are many false shapes for that.

              Astigmatism definitely has different orientations (a 360 degree angle figure) but it affects the direction the blurriness goes. Not the amount of it.

              I also have it but not super bad. For me it’s still much better to have a little blurriness at night than burning my eyes out on a white background (thanks google for popularising the “white on light grey on white” design mantra)

              They can and do. That’s what the optometrist is checking when they flip the little lenses around and rotate them and it’s obvious it wasn’t to change the focus. It doesn’t get more/less clear unless you have astigmatism when they’re flipping those ones (at least in the same way).

      From an objective point of view, if your phone has an OLED screen, it uses less energy to emit less light. So in that case, dark mode can matter in that it’ll save battery life.

      That said, I’m seeing a lot of aesthetical defense.

      It’s just easier to read light on dark, for so many. According to this, I should find light mode more accessible; but for myself and my legally blind friend, we find light on dark much easier to read and navigate.

        Not all dark modes are created equal. Some dark modes use a color theme that is illegible for people with color blindness. Many dark modes don’t have enough contrast for the legally blind. Now, properly well designed dark themes with accessibility in mind will be more readable. But for some people with certain forms of blindness, black letters over white are more readable than what some apps and webpages implement as a dark mode.

            Not OP, but if you want to peek at what the law considers decent design for this stuff, look up WCAG and AMA requirements on contrast. Not only will you have a better idea of what’s legible for folks, but you’ll be able to tell when a business or website isn’t following accessibility laws (they only HAVE to follow them if they’re government related sites or public services though, iirc)!

      It depends on the context, but I often prefer light mode with screen brightness set to very low. Easy on the eyes. Never experience the shock of going from a dark page to a bright page. Bonus is that battery is rarely an issue for me (usually 80% remaining on normal days).

      I have a theory that people who complain about light mode haven’t figured it’s possible to just reduce the screen brightness.

      I can’t handle dark mode on most screens especially in daytime. It strains my eyes trying to read light text in dark background, even more so when there’s ambient light. I prefer a solarised light mode for IDEs, with anything else I make do. I’ve spent hours trying to find a usable dark theme for VS Code, and I’ve always ended up going back to light.
