      Hello,
      I know darkroom mode inverts the colors and makes the screen even more red than the lowest color setting of 1900K, but I was wondering what the actual color temperature of this mode is. I couldn't find this information in your FAQ.

        I think it's 1200K because the Windows version can go as warm as 1200K and the red of Dark Room Mode is identical.

          1200K still has a tiny bit of green in it, which still lets you see a bit of color. It's essentially the same as "all red" but gives a lot more detail.

          For sRGB, you have to be below 850K to be "all red".

          In some implementations we use 800K and in others we hardcode "nothing but red".

            @herf Sorry I should have specified, I meant for the iOS sideloaded app (I downloaded it before the app was pulled).

            I discovered that if you go into Settings under Accessibilty and toggle Invert Colors on and then back off that it will uninvert the colors but leave the redder hue of darkroom mode. This is actually really useful for someone like me who is REALLY sensitive to light at night.

            I combine that with the Low Light Zoom filter (also under Accessibility), which puts a filter over the screen to dim it even further, and the result is a device that is both very red and very dim, which for me is a really good combination!

            (If you set both the low light filter and invert colors as home button shortcuts, you can toggle these settings fairly quickly.)

            This is why I was curious what the actual color temperature of darkroom mode is, since I've started using it this way at night.

              Yeah internally it just uses 800K, but it doesn't matter as it's entirely red by that point. We could go to 500K and it wouldn't make any difference!

                @herf Yeah I remember when you and lorna told me about the pure red kelvin level, very cool to know.

                  Yeah, I would love to see the option to use 800K return to the Windows version of f.lux.

                    @TwoCables The contrast is very different but you can invert darkroom mode. Since I use the magnifier a good bit, just do Ctrl Alt I. That's actually the ONLY way I know to invert the screen colors.

                      I don't want to mess with my contrast. Due to using NVIDIA's Digital Vibrance at 74%, I already have to press Alt+Page Down one time after switching to 1200K. If I don't do that, then everything is a bit washed out.
