The red color filter for outside when trying to preserve night vision is a great tip. Some apps have this built-in but much better to have the OS change it everywhere.

Recommend creating a Shortcut to toggle this setting.

Not just for outside, but also at public gatherings like concerts! I went to a concert last month and used a red color filter to record a couple short videos without being a big distraction to the audience behind me.

Dim backlight + Red color filter can make the screen almost invisible to those around you.

I made a Shortcut that drops the white point, turns on the red filter, zeroes the audio and turns down the brightness. On wake-up it reverses these.

It’s attached to an automation for sleep and wake focus it works really well. I added an explicit run requirement for wake so that I could sleep in without getting blasted in the face with white. There’s a notification with a run button which I can wait until I’m truly up to hit.

Thanks for the reminder. Wish I had remembered this feature during the aurora photography I was doing. I set the phone brightness to the lowest setting but the red filter would have helped even more.

The issue I've seen when the app itself offers a red filter is if that app calls an OS native widget like a keyboard does not get filtered. The system level accessibility feature does filter the OS widget. I would almost rather the app's setting to just enable the OS filter, but I can understand why that might not be possible.

You can also add it to the accessibility shortcut, available anywhere by triple-clicking the power button.

I think you can just add it to Control Centre, no need for shortcuts. I made an app for reading in the dark, minimising the amount of light hitting your eyeballs, but I'm still using the red color filter every night.

The app is overall darker and more "strict" with how it handles content (esp. images) though: https://untested.sonnet.io/Heart+of+Dorkness and midnight.sonnet.io

Overall, reduced the number of photons is a fun metric to play with when building something/messing with prototypes.

Huh?

It's not built-in?

Android (or at least Moto) has it for years, auto enable on the schedule or the sunrise/sunset.

There's a built in "night shift", but that just changes the colour temperature, it doesn't make everything monochrome red.

No, that's (part of) what Color Filters is for.

iOS has also had “Night Shift” for several years. The parent is talking about a full on red colour filter, like astronomers might use.

Kinda feels like you could’ve done more of a cursory glance to see what functionality was actually being talked about before going for the “Android already does this!!” comment.

Kinda feels like you could've be more like [0] than being an ass, while totally missing what I was surprised about the lack of automagik, not of the feature itself.
