10 Tech How-To

How to Invert Colors on iPhone with Siri

Guide 10-22405 · Updated · Step by step

If you need to quickly switch your iPhone to a high-contrast, dark-on-light display, you can use Siri to turn on the Smart Invert or Classic Invert color filter. This is useful for reading at night, reducing eye strain, or making the screen easier to see in bright light. You’ll need an iPhone running iOS 13 or later, with Siri enabled and an internet connection (for on-device processing, though some older models may require it).

What You’ll Need

  • An iPhone with iOS 13 or later (Siri’s “Hey Siri” or Side button support).
  • Siri enabled in Settings > Siri & Search.
  • An active internet connection (for Siri to process the request, though it may work offline on newer models).

Step-by-Step

  1. Wake Siri. Press and hold the Side button (on Face ID models) or the Home button (on models with Touch ID), or say “Hey Siri” if you have that enabled.
  2. Say the command. Clearly say one of the following:
    • “Turn on Smart Invert” – this inverts colors but keeps images, media, and some apps looking natural.
    • “Turn on Classic Invert” – this inverts all colors, including images and videos.
    • “Turn off Invert Colors” – to disable either filter.
  3. Wait for confirmation. Siri will respond with a confirmation and the screen will change instantly. If you don’t see the change, check that the command was recognized (you’ll see the Siri waveform on screen).
  4. Toggle between modes. To switch from Smart to Classic or vice versa, just say “Turn on Classic Invert” while Smart Invert is active, or use the Control Center toggle (see Tips).
  5. Turn off. Say “Hey Siri, turn off invert colors” or “Turn off Smart Invert” to revert to normal.

Common Mistakes

  • Saying “invert” without specifying the type. Siri might not know which one you want. Always say “Smart Invert” or “Classic Invert”.
  • Using the wrong button. On iPhones with Face ID, the Side button is the one on the right. On older models, it’s the Home button. Pressing the wrong button may trigger Apple Pay or Emergency SOS.
  • Expecting Siri to work without internet. Some Siri requests require a connection, especially on older iOS versions. If it fails, try again with Wi-Fi or cellular data on.
  • Confusing with Dark Mode. Invert Colors is not the same as Dark Mode. Dark Mode only changes system backgrounds and supported apps, while Invert flips all colors.

Tips

  • Use Control Center for a quick toggle. Go to Settings > Control Center > Customize Controls, add “Accessibility Shortcuts”, then triple-click the Side or Home button to bring up a menu where you can toggle Invert Colors without Siri.
  • Set up a Siri shortcut. You can create a custom Siri phrase in the Shortcuts app to toggle invert colors with a single command like “Night mode”.
  • Know the difference. Smart Invert is usually better for everyday use because it keeps photos and videos looking normal. Classic Invert is more aggressive and can make some apps unreadable.
  • Use with accessibility. If you need this often, consider enabling the Accessibility Shortcut (triple-click) for faster access.

Troubleshooting

If Siri doesn’t respond or the command fails:

  • Check Siri settings. Go to Settings > Siri & Search and make sure “Listen for ‘Hey Siri’” or “Press Side Button for Siri” is enabled.
  • Restart Siri. Toggle Siri off and on in Settings, then try again.
  • Update iOS. Older versions may have bugs. Go to Settings > General > Software Update to check for updates.
  • Use manual method. If Siri still fails, go to Settings > Accessibility > Display & Text Size and toggle “Smart Invert” or “Classic Invert” manually.
  • Check for restrictions. If you’re using Screen Time, ensure that Siri isn’t restricted under Content & Privacy Restrictions.

Frequently Asked Questions

Does Siri work offline for this?

On iPhones with an A12 Bionic chip or later, Siri can process many commands on-device, including this one, so it may work offline. Older models may require an internet connection.

Can I invert colors only for certain apps?

No, the invert filter applies globally. However, Smart Invert tries to preserve images and some app content, so it may look less disruptive in apps like Photos or Safari.

Will inverting colors affect battery life?

On OLED iPhones (X and later), using Classic Invert with a dark background can reduce battery usage because black pixels are turned off. Smart Invert may also help if most of your screen is dark.

Why does my screen look weird after turning off invert?

Sometimes the screen may appear to have a yellow or blue tint. This is normal as the display adjusts. If it persists, restart your iPhone or check that Night Shift and True Tone are set to your preference.

Can I schedule invert colors to turn on automatically?

Yes, you can use the Shortcuts app to create an automation that toggles invert colors at a specific time or when you open a certain app.

Is there a difference between Smart Invert and Classic Invert?

Yes. Smart Invert reverses colors except for images, videos, and some app-specific UI elements, making it more usable. Classic Invert reverses everything, which can make media look like a negative.
