Change your iPhone's color settings in three places

Your iPhone has three separate color systems you can adjust: the overall display color temperature (called True Tone), the interface colors (Light or Dark mode), and accessibility color filters for vision needs. Most people want to change between Light and Dark mode, which flips the entire interface from white backgrounds to dark ones. You can also adjust how warm or cool your screen looks, or explore color filters if you have color blindness or light sensitivity.

The fastest way is through Control Center — swipe down from the top right corner and tap the brightness icon to access Dark mode. For more detailed control, go to Settings and choose Display & Brightness. If you need color filters for accessibility, those live in Settings under Accessibility > Display & Text Size.

Key Takeaways

  • Dark mode inverts your interface to dark backgrounds and light text, and you can toggle it when ready from Control Center or set it to turn on automatically at sunset.
  • True Tone adjusts your screen's color temperature to match your lighting, making it warmer indoors and cooler outdoors — this is separate from Dark mode.
  • Color filters in Accessibility let you simulate color blindness modes or reduce blue light, and you can turn them on with a triple-tap of the side button for quick access.
  • You can schedule Dark mode to switch automatically at a specific time or at sunset, so you do not have to remember to change it manually.

Turn Dark mode on or off from Control Center

The quickest way to switch between Light and Dark mode is through Control Center. Swipe down from the top-right corner of your screen (or swipe up from the bottom on older iPhones). Look for the brightness slider — it shows a sun icon on the left and a moon icon on the right.

Tap and hold the brightness slider. A menu appears with additional controls. You will see a moon icon labeled "Dark mode" — tap it to turn Dark mode on when ready. Tap it again to return to Light mode. This change takes effect right away across your entire phone.

Set Dark mode to turn on automatically at sunset

Instead of switching manually, you can tell your iPhone to use Dark mode only during evening hours. Go to Settings > Display & Brightness. At the top, you will see two large buttons: one labeled "Light" and one labeled "Dark." Below those buttons is a section called "Automatic."

Tap "Automatic." Your phone will now switch to Dark mode at sunset and back to Light mode at sunrise, based on your location. If you prefer a specific time instead, tap "Options" and choose "Custom Schedule," then set the exact times you want the switch to happen. Your phone will flip between modes at those times every day.

Adjust True Tone to warm or cool your screen

True Tone is a separate setting that adjusts your screen's color temperature to match the light around you. It makes your screen warmer (more yellow) indoors under warm lighting, and cooler (more blue) in daylight. This is different from Dark mode — True Tone works in both Light and Dark modes.

Go to Settings > Display & Brightness. Scroll down and toggle "True Tone" on or off. When it is on, your screen automatically adjusts throughout the day. If you find it distracting or want a consistent color temperature, turn it off. You can also use the Night Shift feature (in the same menu) to manually add warmth to your screen in the evening, which some people find easier on their eyes before bed.

Use color filters for color blindness or light sensitivity

If you have color blindness or find bright screens uncomfortable, color filters let you adjust how colors appear. Go to Settings > Accessibility > Display & Text Size. Scroll down to "Color Filters" and toggle it on.

Tap "Color Filters" again to see your options. You can choose "Grayscale" (removes all color), "Red/Green Filter" (for red-green color blindness), "Green/Red Filter" (for a different type of red-green blindness), or "Blue/Yellow Filter" (for blue-yellow color blindness). Select the one that works for you, then adjust the intensity slider below it — move it left for a lighter effect or right for a stronger one. The preview updates as you move the slider so you can see the effect in real time.

Create a quick shortcut to toggle color filters

If you use color filters regularly, you can set up a triple-tap shortcut so you do not have to dig into Settings every time. Go to Settings > Accessibility > Accessibility Shortcut. Scroll down and tap "Color Filters" to add it to your shortcut list.

Now, whenever you triple-tap the side button (or home button on older iPhones), your color filters will toggle on and off. This is useful if you want to switch between filtered and normal view quickly — for example, to check a color in an app and then return to your filtered view. You can add multiple accessibility features to this shortcut, and they will all toggle together.

Reduce blue light with Night Shift

Night Shift is a built-in feature that adds warmth to your screen by reducing blue light, which some research suggests can help you sleep better if you use your phone before bed. Go to Settings > Display & Brightness and scroll down to "Night Shift."

Tap "Night Shift" to turn it on when ready. You can also set a schedule — tap "Scheduled" and choose "Sunset to Sunrise" to have it turn on automatically in the evening, or "Custom Schedule" to set specific times. Use the "Color Temperature" slider to adjust how warm the screen gets. Warmer (more yellow) is stronger, and cooler (more blue) is lighter. Unlike True Tone, Night Shift does not adjust automatically based on your surroundings — it applies a fixed warmth level you control.

Frequently Asked Questions

Can I use Dark mode and True Tone at the same time?

Yes. Dark mode changes your interface to dark backgrounds, and True Tone adjusts the color temperature of your screen. They work independently, so you can have Dark mode on with True Tone on or off. True Tone will still warm or cool your screen based on your lighting, even in Dark mode.

Why does my screen look different on different apps?

Some apps do not fully support Dark mode and will stay light even when Dark mode is on. Older apps especially may not have been updated to work with Dark mode. Developers control whether their apps respond to your Dark mode setting, so you may see a mix of light and dark interfaces depending on which apps you use.

Does Night Shift help you sleep?

Night Shift reduces blue light, which some studies suggest can help your body produce melatonin in the evening. However, the effect is modest — the bigger factor is how much time you spend on your phone before bed. Night Shift is worth trying if you use your phone in the evening, but it is not a replacement for putting your phone down earlier.

What is the difference between Dark mode and Low Light mode?

Dark mode inverts your interface to dark backgrounds with light text. Low Light mode (in Accessibility) is a separate feature that dims your entire screen significantly and is designed for people with light sensitivity or certain eye conditions. You can use both at the same time if needed.

Can I set different color filters for different times of day?

No. Color filters explore one setting at a time — you cannot schedule them to change automatically. However, you can use the triple-tap shortcut to toggle them on and off quickly, or you can turn them on manually through Settings whenever you need them.
