You can set per-app Accessibility settings as well, but sadly Color Filter is a global configuration.

You could set up an "on app launch" automation shortcut for Maps to alter the Color Filter setting, but I'm not sure how you'd automate switching it back after closing/leaving Maps. I don't use the automations, but instead have a shortcuts widget with "toggle greyscreen" (among others) which is sufficient for me most of the time.

You can have 2 automation, one which enable grayscale when certain apps are open and one that disable it when the apps are closed. It’s under shortcuts > automation > app > is closed.

I put this in a different comment but you can also have a single automation that toggles the setting for those apps on open and close. This way you have a single list of apps to maintain.

You can make the greyscale toggle on triple power/home button, or via control centre. Thus, you can have it on most of the time, toggle it to look at a map, then toggle it back.

That’s a perfect solution for me, thanks for the idea!

I made a Shortcut for it and added it to the home screen. I found the triple click too fiddly, and the control center option to be not present enough.

You can also have a Shortcut that toggles the setting when you open and close specific apps.

I just did it and it’s very simple:

- in the Shortcuts app, go to Automations

- add a new one and pick “App” as the trigger

- choose the apps you want color in and pick “run immediately” and on open and close

- on the next screen pick “new blank automation”

- in the new shortcut add “Set Color Filters” and set to toggle

You can also make different automations for open and close, but toggle works as long as you toggle the effects manually. But in this case you can just toggle it back manually.

thanks

Probably a bug but my browser in dark mode actually inverts image and video into something like posterized predator vision. Since I was looking for grayscale anyway, I’ve kept it and not looked back.

Even though phone manufacturers and service providers are doing everything they can to limit the availability of smaller, reasonably sized phones.. even the huge phone I get forced into using is just incredibly frustrating to browse the web with. Besides the usual gdpr harassment taking up a third of every screen, mobile just increases the thirsty demands for me to install apps, etc.

Might as well drive home the point that friction is inevitable rather than making it easier to start an interaction that’s only going to annoy me. If I need to do anything other than view simple text, I already know I’ll have to get out the laptop

Try turning down the color saturation. For me ~ 25% of original saturation is sufficient for using UIs that use color information.

I had the same annoyance as you, switching back and forth wasn't pleasant, and I'd forget. I think part of the reason is that switching between 0% <-> 100% saturation doesn't give room to adapt. It feels like a bandwidth of information is missing. But, if the colorspace is barely noticeable, your brain will fill in the colors for you with the information it gets... and the high-saturation default color-set would start to appear abrading and unnatural.

Actually, my primary usage of my phone is photography. I'm assuming the saturation will have an impact on Photography as I won't be seeing the ideal colors.
