Tangential: I've been playing around with the color blindness filters on my iPhone, and the grayscale filter had me thinking for a moment. I've set it to 50%, set up the accessibility shortcut (triple-click on the home button) to toggle it, and found myself using my phone with the filter on basically 99% of the time. It's been a couple of months, and I've noticed that the oversaturated colors were making me slightly agitated, somehow captivating my attention. I sometimes disable the filter to look at a particular picture, or to figure out a detail in some context where the colors are already desaturated. Now my only wish is that it was less linear, maybe like a compressor in audio - maintain detail until it starts approaching the ceiling. It may be a good idea if you'd consider <thelightphone.com> but don't want to switch.

I bet there's a way to accomplish what you're looking for with ICC profiles. They allow arbitrary functions and LUTs in addition to standard matrix math. There's typically a way to set this for your OS, an individual image, and I'm pretty sure an individual app as well (but I'd imagine only your own). Edit: Actually, this may not be editable on iOS, but it is on macOS, Windows, probably Linux, and it looks like Android too. https://en.wikipedia.org/wiki/ICC_profile https://en.wikipedia.org/wiki/ICC_profile

You can do this on Android as well (manufacturer results may vary...) This is on Android 14, but I initially turned it on in an earlier version: 1. unlock the Developer options (you can search this; depends on OS version) 2. in Developer options, scroll down to "simulate color space", choose grayscale 3. back to main settings --> Accessibility --> advanced, there is an "accessibility button" option 4. set that to "color correction" Now I have a small icon (looks like a person) that I can use to toggle monochrome. Indeed it was someone I heard on a train who had this turned on for iPhone as described above for the same reason ("lowers the dopamine response", he explained to the conductor) that intrigued me into looking into it Samsung also has a decent automation infrastructure ("modes and routines"), so I set that up to automatically disable the color correction / grayscale in certain apps (camera, photos, maps, etc.)
