I feel like Apple really dropped the ball on that. Neither of the two reverse video modes remove blue. Flux works great on OSX and the people that make it really care about low-light accessibility, I'm typing this on my Dark Mode MacBook that I bought specifically to live at my bedside. Nothing else compares.

iPhone's accessibility page for color filters looks like a clown car show of useless features. If anyone's found the magic configuration that makes that shitshow usable please share it.

What I've found is:

1. You can set "reduce white point" to reduce white light 2. You can set a color tint filter and move the hue far to the left. That's the red/orange area. Set intensity to max. 3. You can set the accessibility shortcut to turn these on. (This one is lacking - it slows app switching on non-X devices)

I don't know how to assess actual colour spectrum output, mind you. Does this seem effective?

I leave night shift and true tone on as well.

I think the problem I had with this one is that any time you're looking at something that would be white, instead it's super bright red. Without something that actually changes the displayed colors, you're stuck reducing the contrast so much everything's barely legible. But I'll give it another shot, thanks.

Yeah I actuslly go for a dark orange. The red wasn’t really useable. Reduce whit epoint is actually my favourite part though.
