Short answer
To turn on grayscale on iPhone, go to Settings > Accessibility > Display & Text Size > Color Filters, turn on Color Filters and tap Grayscale. To switch it on and off fast, add Color Filters to Settings > Accessibility > Accessibility Shortcut and triple-click the side button. To schedule it, use a Time of Day automation in the Shortcuts app. Grayscale changes how the screen looks; it doesn't limit or block any app.
To turn on grayscale on iPhone, go to Settings > Accessibility > Display & Text Size > Color Filters, turn on Color Filters and tap Grayscale. To switch it on and off in a second, add Color Filters to the Accessibility Shortcut and triple-click the side button.
The steps are the same in iOS 26 and iOS 27. Scheduling it is the part that changed: below you’ll find how to make your iPhone go black and white at a set time with the Shortcuts app, how to undo it when it turns gray by surprise, and what grayscale does and doesn’t do for your screen time. Everything was checked against Apple’s iPhone User Guide, Shortcuts User Guide and Apple Support on November 2, 2026.
How do you turn on grayscale on iPhone?
On iOS 26 and iOS 27:
- Open the Settings app.
- Tap Accessibility, then Display & Text Size.
- Tap Color Filters and turn on Color Filters.
- Tap Grayscale.
Your whole screen turns black and white right away. Apple’s guide describes it as a filter “to view the entire screen in grayscale”, and the same screen offers three filters for color vision deficiencies plus Color Tint. You can drag the intensity slider if one appears. Apple also notes that color filters “can change the look of images and videos”, so photos look gray too while it’s on.
How do you turn grayscale on and off quickly?
The fastest way is the Accessibility Shortcut, which Apple documents for both iOS 26 and iOS 27:
- Go to Settings > Accessibility > Accessibility Shortcut.
- Select Color Filters.
- Triple-click the side button on an iPhone with Face ID (or the Home button on an iPhone that has one).
If Color Filters is the only feature you select, Apple says it turns on or off “immediately” when you triple-click. If you select several, a menu asks which one to toggle. Apple’s support article on display settings confirms that Color Filters can be turned on or off with the Accessibility Shortcut.
Control Center is the other option. Apple’s guide says you can open Control Center, tap the edit button in the top-left corner, tap Add a Control, and scroll to the categories of controls for accessibility and vision. Apple doesn’t list each control by name, so look there for a color filters control. If you don’t see one, the triple-click shortcut is the documented route.
How do you schedule grayscale on iPhone?
There’s no schedule switch inside Color Filters. You build one with the Shortcuts app: an automation that turns Color Filters on at night, and a second one that turns it off in the morning. First pick Grayscale in Settings as above, so that turning Color Filters on gives you grayscale.
A note on the action: Apple’s Shortcuts User Guide doesn’t list the Color Filters action by name, so we can’t quote its exact label. In the action search, type “color filters” and pick the action that sets Color Filters, then make sure it’s set to turn them on.
On iOS 26 (Apple calls it a personal automation):
- Open Shortcuts and tap Automation. If you already have automations, tap the add button in the upper-right corner.
- Tap Create Personal Automation.
- Choose Time of Day, set a time such as 9:00 PM, set Repeat to Daily (or Weekly for certain days), then tap Next.
- Tap Add Action, search for “color filters” and add the Color Filters action, set to on.
- Tap Next, then Done.
- To stop the confirmation notification: tap the automation, turn off Ask Before Running, tap Don’t Ask, then Done. Time of Day is on Apple’s list of automations that can run without asking.
- Repeat with 7:00 AM and the action set to off.
On iOS 27, Apple’s English Shortcuts guide describes a different layout: automations are added to a shortcut instead of living on their own. Create a shortcut with the Color Filters action, tap Edit, then Automation, and choose Time of Day. To let it run without asking, Apple says to tap the shortcut, tap Edit, tap the settings button, tap Privacy and turn on Allow Running When Locked. To see all your automations, tap Automation in the Shortcuts app. Apple’s Portuguese and Spanish iOS 27 pages still show the iOS 26 steps, so if your screens look like the iOS 26 list above, follow that instead.
Can grayscale turn on with a Focus?
Yes, through the same automation screen. In iOS 26, Apple lists Focus among the setting triggers, with When Turning On and When Turning Off. Make one automation that turns Color Filters on when your evening Focus turns on, and one that turns it off when the Focus ends. Then give the Focus its own schedule: in Settings > Focus, pick the Focus and tap Add Schedule.
One catch: Apple’s list of automations that can run without asking names Do Not Disturb but not Focus in general, so a Focus automation may still ask you to confirm. Apple’s iOS 27 page doesn’t list the triggers in detail. Test it once before you rely on it.
Why did my iPhone suddenly go black and white?
Usually one of these, all documented by Apple:
- You triple-clicked the side button. If Color Filters is in the Accessibility Shortcut, a triple-click toggles it. Triple-click again.
- Color Filters is on. Go to Settings > Accessibility > Display & Text Size > Color Filters and turn off Color Filters.
- Zoom has a grayscale filter. Zoom has its own filter, separate from Color Filters. Go to Settings > Accessibility > Zoom and set Zoom Filter to None, or turn off Zoom.
- An automation ran. In iOS 26, open Shortcuts, tap Automation, tap the automation and turn off Enable This Automation. In iOS 27, open the shortcut and remove its automation trigger.
- Back Tap or the Action button. Apple says both can be set to an accessibility feature. If you set one up, a tap or a press may have turned it on.
Night Shift won’t fix it. Apple notes that Night Shift removes color filter effects “except grayscale”.
Does grayscale reduce screen time?
We can’t promise that it does, and neither does Apple. Apple documents grayscale as an accessibility setting for seeing the screen more easily, not as a screen time tool, and we didn’t find an Apple page that says anything about grayscale and phone use.
The idea behind the tip is simple: in black and white, colorful app icons, red notification badges and bright feeds stand out less. If that sounds useful, treat it as an experiment. Turn it on for your evenings for a week and compare your Screen Time report with the week before. Your own numbers will tell you more than any general claim.
What grayscale can’t do is stop you from opening an app. Instagram, TikTok and YouTube all work exactly the same in gray. If the habit is opening a feed without thinking (we wrote about why doomscrolling is so hard to stop), color is only one part of the pull.
Grayscale, Screen Time, Focus or an app blocker?
| Tool | What it changes | Can you still open the app? | Can it run on a schedule? | Cost |
|---|---|---|---|---|
| Grayscale (Color Filters) | How the whole screen looks | Yes, every app works as usual | Yes, with a Shortcuts automation | Built into iOS |
| Screen Time (App Limits, Downtime) | Access to apps after a limit or during set hours | Apple’s iOS 26 guide: “By default, Screen Time limits can be ignored once reached” | Yes, built in | Built into iOS |
| Focus | Which notifications and people can reach you | Yes. Focus silences notifications; it isn’t an app block | Yes, with Add Schedule | Built into iOS |
| App blocker (like Calma) | Access to the apps you pick, at the times you pick | Not during a scheduled block: a calm block screen appears | Yes | Calma: blocking needs Calma Pro, 3-day free trial |
They stack well. Grayscale makes the phone less eye-catching, Focus quiets the alerts, and a blocker handles the two or three apps you open on autopilot. If you’re not sure which layer fits your problem, our guide on choosing between Focus and Screen Time walks through it.
Where does Calma fit?
We make Calma, so weigh this with that in mind. Calma doesn’t change your screen colors. It does the part grayscale can’t: it rests only the apps you pick (say, Instagram and TikTok) at the times you choose, like the Night Peace routine from 10 PM to 7 AM. Opening one shows “[App] is resting.” with a single Back to calm button on scheduled blocks and daily limits. You can end a focus session early with a 3-second hold, or switch any routine off in the app.
A setup some people like: grayscale from 9 PM through a Shortcuts automation, and Calma resting the feeds from 10 PM. For more evening ideas, see our evening wind-down routine without feeds.
Calma is built on Apple’s Screen Time framework, so its blocks run even when the app is closed. It’s iPhone only, needs iOS 18 or later, blocks apps rather than websites, and blocking needs Calma Pro, with a 3-day free trial for eligible new subscribers.

Grayscale on iPhone: quick answers
Is grayscale the same as black and white mode?
Yes. iPhone has no setting called “black and white mode”; the Grayscale option in Color Filters is what people mean.
Can I make only one app grayscale?
Apple’s guide describes the filter as applying to the entire screen, and we found no Apple page about applying it to a single app.
Does Night Shift turn off grayscale?
No. Apple says Night Shift removes color filter effects except grayscale, so both can be on together.
Does grayscale change my photos?
Apple says color filters change how images and videos look. Turn the filter off to see them in color again.
Can I make it less gray?
Apple’s support article says you can adjust the intensity of any color filter with the Intensity slider.
