    It’s only going to save power if you’re using an oled, since for most lcd screens the backlight is on whether you display black or white.

    All my websites are jet black, and the black is only really black on my phone which has an oled screen.

    Either way, it’s just greenwashing. These companies are only pretending to give a crap so they can get brownie points with people who can’t see what they’re doing.

      Most lcds take a tiny bit of current to darken a pixel I think. The ground state would be white and power is used to get the lcd in the state where it changes the lights polarization to get it blocked by the polarization filter in front of it

        I assume that would depend on the polarization of the screen. I wonder which is more common?

          Yes, I think it’s this way around because precision is higher at higher power, so the minor deviations close to no voltage applied are hidden in minute white variations, while near blacks are way more precise. But don’t quote me on that
