What You Can Change on Your iPhone Display

You can adjust your iPhone's screen color in several ways without replacing the physical display. The most common changes are True Tone (which shifts color temperature based on your lighting), Night Shift (which adds warmth to reduce blue light), and Color Filters (which explore tints for accessibility or preference). You can also adjust brightness, contrast, and enable Grayscale if you want a black-and-white screen. Each of these settings lives in different places in your Settings app, and most take effect when ready.

These are software adjustments—they change how your phone displays color without touching the hardware. If your screen is physically damaged or the display itself has failed, these settings won't help, and you would need a hardware repair instead.

Key Takeaways

  • True Tone automatically adjusts your screen's color temperature to match your environment and is found under Settings > Display & Brightness.
  • Night Shift adds a warm orange tint to reduce blue light in the evening and can be scheduled to turn on and off automatically.
  • Color Filters let you explore a tint across your entire screen and are useful for accessibility or personal preference.
  • You can control most of these settings from Control Center for quick access without opening Settings each time.

Turn True Tone On or Off

True Tone shifts your screen's color to match the ambient light in your environment. In warm lighting, your screen becomes warmer; in cool lighting, it becomes cooler. This reduces eye strain for many people because your screen won't look unnaturally blue in a warm room.

Open Settings and tap Display & Brightness. Look for the True Tone toggle and switch it on or off. The toggle will turn green when True Tone is active. You can also control True Tone from Control Center: swipe down from the top-right corner of your screen (or up from the bottom on older iPhones), find the brightness slider, press and hold it, and tap the True Tone icon to toggle it.

True Tone works on iPhone XS and newer models. If you have an older iPhone, this setting won't appear in your Display & Brightness menu.

Enable Night Shift to Reduce Blue Light

Night Shift adds a warm, orange-tinted filter to your screen. It's designed to reduce blue light exposure in the evening, which some people find helps them sleep better. Unlike True Tone, Night Shift is a manual filter you control—it doesn't respond to your environment.

Go to Settings > Display & Brightness > Night Shift. Tap the toggle to turn it on when ready. You'll see the screen take on a warmer tone right away. To schedule Night Shift to turn on and off automatically, tap Schedule and choose Sunset to Sunrise (which uses your location) or Custom Schedule to set exact times. Drag the Color Temperature slider left for less warmth or right for more warmth.

You can also control Night Shift from Control Center. Swipe down from the top-right corner, press and hold the brightness slider, and tap the Night Shift icon to toggle it on or off without opening Settings.

explore Color Filters for Accessibility or Preference

Color Filters overlay a tint across your entire screen. They're built for accessibility—for example, people with color blindness can use filters to distinguish colors more easily—but you can use them for any reason. Options include Grayscale (black and white), Red/Green filters, Blue/Yellow filters, and others.

Open Settings > Accessibility > Display & Text Size > Color Filters. Tap the toggle to turn Color Filters on. Then tap Filter and choose the type you want: Grayscale, Red/Green, Blue/Yellow, Deuteranopia, Protanopia, or Tritanopia. Each one shifts colors differently. Drag the Intensity slider to make the effect stronger or weaker. Tap the back arrow when you're done.

Color Filters stay on until you turn them off. You can add a shortcut to toggle them from Control Center: go to Settings > Accessibility > Accessibility Shortcut, scroll down, and check Color Filters. Then triple-tap the side button (or home button on older iPhones) to toggle the filter on and off quickly.

Switch to Grayscale for a Black-and-White Screen

Grayscale removes all color from your screen, leaving only black, white, and shades of gray. Some people use this to reduce distractions or to preserve battery life slightly. Grayscale is technically a type of Color Filter, but it's straightforward enough to set up on its own.

Go to Settings > Accessibility > Display & Text Size > Color Filters. Turn on the toggle, then tap Filter and select Grayscale. The intensity slider won't appear for Grayscale—it's either on or off. Your entire screen will turn black and white when ready.

To turn Grayscale off, go back to the same menu and toggle Color Filters off. If you use Grayscale often, add it to your Accessibility Shortcut so you can toggle it by triple-tapping your side button.

Adjust Brightness and Contrast

Beyond color, you can change how bright or dark your screen appears and how sharp the contrast is between light and dark areas. Brightness is the most common adjustment—a dimmer screen uses less battery and is easier on your eyes in dark rooms.

To adjust brightness, swipe down from the top-right corner of your screen (or up from the bottom on older iPhones) to open Control Center. Drag the brightness slider up to make the screen brighter or down to make it dimmer. For more detailed brightness settings, go to Settings > Display & Brightness and toggle True Tone on or off, or enable Auto-Brightness to let your phone adjust brightness based on ambient light.

To adjust contrast, go to Settings > Accessibility > Display & Text Size > Increase Contrast and toggle it on. This makes text and icons stand out more sharply. You can also enable Reduce Transparency in the same menu to make backgrounds more opaque and text easier to read.

Use Dark Mode to Change Your Interface Color

Dark Mode changes the background of your apps and system menus from white to dark gray or black. This is different from the color adjustments above—it changes the design of your interface itself, not just a filter over it. Dark Mode can reduce eye strain in low-light environments and uses slightly less battery on iPhones with OLED screens.

Open Settings > Display & Brightness and tap Dark under the Appearance section. Your phone will switch to Dark Mode when ready. You can also set Dark Mode to turn on automatically at sunset and off at sunrise: tap Automatic instead of Dark, then tap Options and choose Sunset to Sunrise.

You can toggle Dark Mode quickly from Control Center without opening Settings. Swipe down from the top-right corner, press and hold the brightness slider, and tap the Dark Mode icon (it looks like a half-moon) to switch between Light and Dark Mode.

Frequently Asked Questions

Will changing my screen color drain my battery faster?

True Tone and Night Shift have minimal impact on battery life. Dark Mode may save a small amount of battery on iPhones with OLED screens (iPhone X and newer) because black pixels use less power than white ones, but the difference is usually small. Grayscale and Color Filters also use negligible battery.

Can I schedule different color settings for different times of day?

Yes, but only for Night Shift. You can set Night Shift to turn on at sunset and off at sunrise, or create a custom schedule with specific times. True Tone, Grayscale, and Color Filters don't have built-in scheduling—you have to toggle them manually or use a shortcut.

What's the difference between True Tone and Night Shift?

True Tone responds to your environment and adjusts automatically throughout the day. Night Shift is a manual filter you control and is designed specifically to reduce blue light in the evening. You can use both at the same time—True Tone will adjust the base color, and Night Shift will add warmth on top of it.

Why does my screen look different after I change the color settings?

Your eyes need a few seconds to adjust to a new color temperature. If the change looks too extreme, lower the intensity of Night Shift or Color Filters, or turn True Tone off if it's making your screen look too warm or cool for your taste.

Can I undo a color change if I don't like it?

Yes. Go back to the same menu where you turned the setting on and toggle it off. All color adjustments are reversible and take effect when ready. If you're not sure which setting is causing the change, turn off True Tone, Night Shift, Color Filters, and Dark Mode one at a time until your screen looks normal again.
