Turning your iPhone's screen black and white is one of the cheapest, most-recommended tricks for using your phone less — no app, no settings change to an account, just a built-in accessibility feature most people have never opened. Here's exactly how to turn it on, make it a one-tap shortcut, automate it, and why it actually works.
Quick answer: go to Settings → Accessibility → Display & Text Size → Color Filters, turn the toggle on, and choose Grayscale. Add it to your Accessibility Shortcut so a triple-click of the side button turns it on and off instantly.
Turn on grayscale in Settings
This is an official Apple accessibility feature called Color Filters, not a hidden trick:
- Open the Settings app.
- Tap Accessibility → Display & Text Size → Color Filters.
- Turn on the toggle at the top of the screen.
- Swipe through the filter examples and select Grayscale (the other presets are for color blindness).
- Optionally, drag the Intensity slider to make the effect lighter or stronger.
This turns your entire iPhone — home screen, every app, the camera, everything — black and white immediately, and stays on until you turn it off the same way.
A triple-click toggle
Flipping grayscale on and off through three menu taps gets old fast, which is exactly why Apple lets you attach it to the Accessibility Shortcut:
- Go to Settings → Accessibility → Accessibility Shortcut (near the bottom of the main Accessibility screen).
- Select Color Filters from the list (tap multiple items if you want the shortcut to offer a menu).
- From anywhere on your iPhone, triple-click the side button (or the Home button on older models with one) to toggle grayscale on or off instantly.
You can also add an Accessibility Shortcut button to Control Center if you'd rather swipe down and tap than triple-click.
One thing worth knowing: if your iPhone ever seems to randomly flip into grayscale on its own, Color Filters being bound to the Accessibility Shortcut is the usual cause — a side button triple-clicked by accident in a pocket or bag toggles it. Remove Color Filters from the shortcut list if that keeps happening.
Schedule it automatically
For grayscale that turns on by itself in the evening and off again in the morning, build a Shortcuts automation:
- Open the Shortcuts app and go to the Automation tab.
- Tap +, then choose a Time of Day trigger (for example, 8 PM).
- Add the action Set Color Filters and set it to On.
- Create a second automation for your wake-up time with the same action set to Off.
- Turn off "Ask Before Running" on both so they fire silently.
This pairs well with a screen time calculator check: if most of your scrolling happens at a specific time of day, schedule grayscale to start just before it.
Why grayscale actually helps
Endless feeds are built on variable, colorful rewards — every swipe might surface something unexpectedly bright, funny or dramatic, and that unpredictability is a big part of what makes them hard to put down. Stripping out color removes one layer of that pull: a grid of grayscale thumbnails is simply less visually interesting to swipe through than the same grid in full color, so the automatic, barely-decided swipe gets a little easier to stop. It's not a block and it doesn't change what's on the screen, just how much it grabs you — which is why it pairs well with something that actually removes a feed, rather than replacing one.
Grayscale inside Stillfeed
Stillfeed, our in-app browser that removes Reels, Shorts and Explore from Instagram and YouTube, also has its own Pro grayscale feature. It's not the same thing as the system-wide setting above: Stillfeed's grayscale applies specifically to the feeds and pages you browse inside the app, across every platform Stillfeed opens, without touching the rest of your iPhone. It's one of several Stillfeed Pro focus tools, alongside quiet hours, word filters and a daily time limit, on top of the free Reels-and-Shorts removal every Stillfeed user gets.
If you want your whole phone grayscale, use the system Color Filters setting above. If you want grayscale applied only where the endless-scroll pull actually lives — inside the apps that have feeds — Stillfeed's version does that without affecting your camera roll, your messages, or any other app.

Common questions
How do I turn my iPhone screen black and white?
Go to Settings → Accessibility → Display & Text Size → Color Filters, turn it on, and select Grayscale. It affects the whole phone immediately.
Why is my iPhone suddenly in grayscale?
This is almost always the Accessibility Shortcut being triggered accidentally, usually a side-button triple-click in a pocket or bag, if you've set Color Filters as a shortcut option. Open Settings → Accessibility → Accessibility Shortcut and remove it if this keeps happening.
Does grayscale actually reduce phone use?
There's no large controlled trial proving grayscale alone cuts screen time, but it's a widely recommended, zero-cost friction technique: removing color from a feed makes it marginally less visually rewarding to keep scrolling. It works best combined with something that removes the endless feed itself, like Stillfeed, rather than on its own.
Can I schedule grayscale to turn on automatically?
Yes, using the Shortcuts app's Automation tab with a Time of Day trigger and the "Set Color Filters" action, set once for on and once for off.
Does Stillfeed's grayscale turn my whole phone black and white?
No. Stillfeed's grayscale is a Pro feature that applies only to the platforms you browse inside Stillfeed. For your whole iPhone, use the system Color Filters setting covered above.
Does grayscale work with Screen Time limits?
They are separate features and work together. Grayscale makes the screen less rewarding; Screen Time limits cap the minutes. Limits can be skipped by default, so see how to stop skipping Ignore Limit, and if a limit seems to do nothing, why app limits stop working.
Why did my grayscale schedule stop working?
A Shortcuts automation can be turned off or can ask for confirmation instead of running. Open the Automation tab in Shortcuts and check that both the on and the off automations are enabled and set to run without asking. The automation is separate from Screen Time, so Downtime settings do not affect it.
Will grayscale count against or reset my Screen Time?
No. Color Filters change how the display looks, not what Screen Time measures, so your usage totals and limits stay the same.
