If your Android phone suddenly looks black and white, inverted, unusually warm, or simply too dark, the cause is usually a display or accessibility setting—not a damaged screen. The correct fix depends on what changed: grayscale, color inversion, color correction, a color filter, Night Light, Dark theme, or an automatic Bedtime/Sleep routine.
Start with the symptom that matches your screen, then use the relevant settings path below. Menu names can vary slightly between Pixel, Samsung Galaxy, Motorola, and other Android phones.
Identify the color problem first
| What the screen looks like | Setting most likely responsible |
|---|---|
| Everything is black and white | Grayscale, often inside Bedtime mode or Sleep mode |
| Colors and light areas look reversed, like a photographic negative | Color inversion |
| The entire screen has a yellow, orange, or warm tint | Night Light or a color filter |
| Only some colors look weak or incorrect | Color correction |
| The background is black, but normal colors remain visible | Dark theme—not grayscale |
| Photos, videos, and other media also have strange colors | Color inversion, color correction, or another display filter rather than ordinary Dark theme |
Quick fix: check Android’s main display settings
- Open Settings.
- Tap Display or, on some Pixel phones, Display & touch.
- Open Dark theme and turn it off if the problem is only a dark interface.
- Look for Night Light and turn it off if the display is yellow or orange.
Dark theme changes Android’s system interface and supported apps. It does not normally remove color from photos or videos. A dark background by itself is therefore not evidence that grayscale is enabled.
Turn off grayscale on a Pixel or other standard Android phone
On Pixel phones, grayscale is commonly connected to Bedtime mode rather than ordinary Dark theme.

- Open Bedtime mode.
- Check whether a display option such as Grayscale is enabled, or whether Bedtime mode is currently active.
- Turn off the grayscale display option or disable the Bedtime schedule.
On some Android versions, the relevant controls appear under Settings > Display, inside nighttime display controls. Pixel’s nighttime settings include Dark theme, Night Light, and Grayscale; these are separate functions.
If your phone is black and white only at particular hours, an automatic Bedtime schedule is the likely cause. Android 13 and later can schedule Dark theme through Bedtime mode, while grayscale may also be applied as a Bedtime display option.
Turn off grayscale on a Motorola phone
Motorola provides a specific grayscale control inside Bedtime mode:
- Open Settings.
- Tap Digital Wellbeing & parental controls.
- Tap Bedtime mode.
- Choose Customize.
- Tap Screen options at bedtime.
- Turn Grayscale off.
If the screen returns to color immediately, grayscale was the cause. If it changes back to black and white later, also check the Bedtime schedule and its start and end times.

Color inversion
- Open Settings.
- Tap Accessibility.
- Open Color and motion.
- Tap Color inversion.
- Turn off Use color inversion.
Color inversion produces reversed colors across the device. It is not the same as grayscale and is not the same as Dark theme.
Color correction
If colors are present but particular hues look diminished or changed, open Settings > Accessibility > Color and motion > Color correction, then turn off Use color correction. The exact label may differ on older phones.
Android 16: change Expanded Dark theme back to Standard
Android 16 and later include an Expanded Dark theme option. It can automatically darken interfaces in apps that do not provide their own native dark theme. In some cases, it can also alter images or make text harder to read.

Remove grayscale from Sleep mode
- Open Settings.
- Tap Modes and Routines.
- Open Sleep.
- Under Other actions, find the grayscale action.
- Tap its Remove icon, then tap Done.
This is the setting to check when the Galaxy screen becomes black and white according to a Sleep routine.
Turn off Samsung accessibility color settings
- Grayscale or altered colors: Open Settings > Accessibility > Vision enhancements > Color correction, then turn Color correction off.
- Negative or reversed colors: Open Settings > Accessibility > Vision enhancements, then turn Color inversion off.
- Colored overlay or tint: Open Settings > Accessibility > Vision enhancements > Color filter, then turn Color filter off.
Do not rely on older instructions that call this menu Visibility enhancements. Samsung’s current support instructions use Vision enhancements, although older devices or regional software may use different wording.
Turn off Night Light when the screen is orange or yellow
Night Light changes the display to warmer tones to reduce blue light. It does not create normal black-and-white grayscale.
On a Pixel, use Settings > Display & touch > Night Light, then turn it off. On Motorola phones, expand Quick Settings and tap Night Light to disable it. Also check whether Night Light has a schedule if the warm tint returns automatically.
Samsung may use a different display or eye-comfort feature name, so search Settings for Night Light, Eye comfort, or blue light if the screen remains warm.

Check whether a shortcut turned the setting on
Accessibility features can sometimes be assigned to a button shortcut, volume-key shortcut, Quick Settings tile, or routine. After correcting the display, search Settings for the feature name—such as Color inversion or Grayscale—and review its shortcut or schedule.
Free tools Windows power users keep installed
One-click scans. No signup required.
On Android 17 or later, an external keyboard can toggle color inversion with Action + Alt + I. On a Windows keyboard, the Action key is the Windows key; on a Mac keyboard, it is the Command key. If the screen changes unexpectedly while a keyboard is connected, press the same combination once and check Settings > Accessibility > Color and motion > Color inversion.
What to do if the colors keep changing
- Check schedules: Review Bedtime mode, Samsung Sleep mode, Night Light, and any Modes and Routines automation.
- Check accessibility shortcuts: Look for color inversion, color correction, color filters, and grayscale shortcuts.
- Check Battery Saver: On some phones, Battery Saver can turn Dark theme on automatically. This explains a dark interface, but not usually a black-and-white display.
- Restart the phone: Hold the power button and choose Restart after changing the setting.
- Test a video or photo: If media remains inverted or tinted, inspect color inversion, color correction, and color filters rather than Dark theme.
If the display is still discolored after all software settings are disabled, remove any screen overlay or display-filter app and test the phone in Safe mode. Persistent discoloration that also appears during startup may indicate a display or hardware problem and should be assessed by the manufacturer or a repair provider.

Does Dark theme make an Android phone black and white?
Normally, no. Dark theme changes backgrounds and other interface colors, while grayscale removes color from the display. Check Bedtime mode, Sleep mode, or accessibility color settings for a black-and-white screen.
Why is my Android screen black and white at night?
A scheduled Bedtime mode or Sleep mode is the most likely cause. Check the grayscale option in Bedtime mode on Pixel or Motorola phones, or remove the grayscale action from Samsung’s Sleep routine.

Is Night Light the same as grayscale?
No. Night Light makes the display warmer, usually yellow or orange. Grayscale removes color and produces a black-and-white display.
Why do photos and videos have strange colors too?
Color inversion, color correction, or a color filter can affect the entire display, including media. Ordinary Dark theme generally changes the system interface and supported apps, not the colors in videos.
Why does my Android screen keep returning to grayscale?
Look for an automatic Bedtime or Sleep schedule, a Modes and Routines action, or an accessibility shortcut. Turn off the schedule or remove the grayscale action rather than changing Dark theme.
The Bottom Line
For a black-and-white Android screen, check Grayscale inside Bedtime mode or Sleep mode first. For reversed colors, disable Color inversion; for a colored tint, disable Night Light or a color filter; for unusual individual hues, disable Color correction. A dark background with normal colors is simply Dark theme, which you can turn off from Settings > Display > Dark theme.
