How to Turn Off Blue Light (Night Light) on Windows 10

Windows 10’s blue light filter is called Night light. When it is on, the screen shifts to warmer colors to cut down on blue light, which many people find easier on the eyes in the evening. You can turn it off completely, turn it off for tonight only, stop the automatic schedule, or reduce its strength. This guide covers every option, plus what to do if the screen stays yellow or the setting is grayed out.

Quick Answer

Open Settings > System > Display and switch Night light to Off. To stop it turning back on, click Night light settings and turn off Schedule night light.

Method 1: Turn Off Night Light in Settings

1. Press Windows + I to open Settings (or right-click the desktop and choose Display settings).
2. Click System > Display.
3. Under Color, switch Night light to Off.

If a schedule is on, Night light will switch on again at the next scheduled time. See Method 3.

Method 2: Use the Action Center Button

1. Press Windows + A or click the notifications icon at the right end of the taskbar.
2. Click Expand if you only see a few tiles.
3. Click the Night light tile to toggle it. Blue (highlighted) means on.

Don’t see the tile? Go to Settings > System > Notifications & actions > Edit your quick actions and add it.

Method 3: Stop the Schedule

1. In Settings > System > Display, click Night light settings.
2. Turn off Schedule night light.
3. Or keep the schedule and change it: choose Sunset to sunrise (requires location services) or Set hours and pick your own on and off times.

Method 4: Reduce the Strength Instead

If you like some filtering but the screen looks too orange, open Night light settings and drag the Strength slider to the left. Click Turn on now to preview the change.

Screen Still Looks Yellow?

• Graphics control panel: Intel, NVIDIA and AMD utilities have their own color settings. Reset color, saturation and temperature to default.
• Monitor settings: many monitors have a “low blue light,” “reading” or “eye care” mode in the on-screen menu. Turn it off with the buttons on the monitor.
• Third-party apps: apps like f.lux or vendor utilities can tint the screen. Close or uninstall them.
• Color filters: check Settings > Ease of Access > Color filters and make sure filters are off.
• Color profile: in Color Management (search the Start menu), check for a custom profile and remove it.

Night Light Is Grayed Out

• Update or reinstall your display driver from Device Manager > Display adapters. Night light doesn’t work with the Microsoft Basic Display Adapter.
• Remote Desktop sessions don’t support Night light.
• Restart the PC after driver updates.
• Advanced fix: some users reset stuck Night light settings by deleting its cached registry keys under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\DefaultAccount\Cloud (the entries containing “bluelightreduction”). Back up the registry first.

Is Blue Light Filtering Worth Keeping?

Research on whether screen blue light affects sleep or eye strain is mixed. Many people simply prefer warmer colors at night, while designers and photo editors usually turn Night light off for accurate color. Reducing brightness and taking regular screen breaks can help with eye comfort too.

Frequently Asked Questions

Does Night light affect screenshots?

Is this the same on Windows 11?

Can I use a keyboard shortcut?

There’s no built-in shortcut, but Windows + A opens Action Center where the tile is one click away.
