    Is that really the case? I mean, no matter the amount of bright or dark colors being displayed, the backlight is still on just the same... [Edit] I wasn't thinking about OLED, where each pixel emits its own light.

    Yup, the edit nails it. For LCD, light-mode uses less energy.

      Let's play the "I like/dislike dark mode game". The rules are simple, you get to state in one sentence the most important reason you like or dislike light or dark mode. You get to add one sentence only, not entire paragraphs. Be funny. Be serious. It's up to you. Just stay civil and don't start a religious war over someone else's preference. I'll start: I dislike dark mode because all I can see on a bright sunny afternoon is the dust on my monitor. Your turn.

      I like dark mode because our renovated office space has LED lighting which is much brighter than before, and light text on a dark background is easier for me to read with my visual issues. [bit of a run-on sentence, but that was a requirement]

        Don't you mean OLED? Based on my (quick) readup, OLED is the one that has the individual pixels emitting their own light. Whereas it's LCD that has an "always-on" backlight.

          I like dark mode because I spent a lot of money on an OLED monitor.

                Nope. A low energy image displayed on an OLED is black, since none of the (light-emitting) pixels are emitting light. A low energy image displayed on an LCD is white, since none of the (light-stopping) shutters are powered. The backlight is a given cost, but to get a dark pixel requires that we polarize the light from the backlight such that it cannot pass through the display. On the types of displays found on old watches, calculators etc, the segments appear black because the segment is powered and the light from the environment cannot pass through the display to then reflect on the back of it and return to our eyes. Colour LCDs have a Red, a Green and a Blue channel (passive) filter for each pixel as well as a(n active) shutter for each of the channels. So a fully red image uses as much power as a fully green image or a fully blue image. You can get higher contrast ratios on OLEDs because there's less bleed-through from adjacent pixels and because emitting no light works better than turning an LCD shutter on. I don't know if OLEDs are similar to regular LEDs, in which similar brightness for different colours requires a different amount of power. Blue LEDs for instance, are considerably brighter for a given wattage than red ones. As an interesting side-note, LEDs can be used to *detect* light!

                  I like dark mode because I'm awake a lot during the wee hours, and a dark screen in a dark room is much easier on the eyes.

                  I like bright rooms so I tend to like light mode. I never use my computer without turning on the room lights.

                    I find most people just buy a monitor and don't adjust it in any way, shape or form. I tend to reduce the brightness on my monitors (and phone) as much as possible, and I don't get eye strain or headaches. I can immediately spot a phone or monitor running at full brightness - it's like staring at the sun. Why people don't realize they can control that, I don't know. At least phones tend to have adaptive brightness, but I still reduce it beyond what it chooses.

                    I always found that reducing brightness to the point where the screen is no longer glaring at me also reduce contrast too much for my comfort. Dark mode, on the other hand, is not glaring at me but still maintaining a high contrast. Yes, at least for coding, this is partly because of my editor theme preferences. Though I think the cognitive effect of brighter-colored elements foregrounding and enlarging themselves against darker colors, and vice versa, also helps.

                      I tried now more than a handful of times dark mode (specifically in VS). In general I don't last more than a day, last time I used it for a week, maybe a bit more. One day I decided I couldn't take it anymore. I don't know why. I am now using a beige background, actually now is like a muted mustard color. Why I try dark mode (theme in VS) once in a while? Because I felt it has a lot of detail in differentiating various bits of code and I find that useful, sometimes. And other days I am ashamed as it looks like a circus. Until the day they'll ban it because of privilege reasons, I'll use the white background.

                        Because of low vision, I sit close to the monitor, so that light mode is like staring directly into a 100 watt lightbulb. Bonus answer: Dark mode consumes less energy on emissive displays like OLEDs.

                          I had cataracts. Dark mode was vital to my working. At that time, a white background would overwhelm the text. I've since had the surgery on both eyes and I good now.

                            Interesting. Thanks for the refresher. I did read about that when OLED was still new, but forgot most of the actual implementation. :-)

                              Drop the brightness. That's most people's problem. 2 of my monitors have their brightness at 0. On one, I set the contrast at 40. The other at 75. My *primary* display is a 4K TV, with the brightness at 50 and contrast at 75. People hold up their phones next to them and comment how dark my monitors are. Yes. That's entirely intentional.

                                Thanks for your thoughtful comment, but inverse video works better for me. High contrast with the background plus low overall brightness, and videos don't look washed out.
