Quick fix: Open Settings → System → Display → toggle off Night light. If toggle is off but screen stays yellow: open Night light settings → Turn off now. Still yellow? Restart graphics driver (Win+Ctrl+Shift+B). If a third-party color tool (f.lux, Iris) is installed, exit it from system tray.

Night Light tints your display warm (less blue) to reduce eye strain at night. Sometimes the schedule gets stuck, or the toggle off doesn’t take effect. Multiple causes: Windows display driver glitch, schedule misconfiguration, conflicting third-party app, ICC color profile issue.

Symptom: Windows 11 screen has yellow/orange tint that won’t go away even after disabling Night Light.
Affects: Windows 11 (and Windows 10).
Fix time: ~5 minutes.

What causes this

Night Light is a Windows display gamma adjustment that warms the screen. The setting is stored in registry; if Windows fails to write the “off” state, the tint persists. Or, GPU driver caches the gamma table and doesn’t refresh. Third-party apps (f.lux, Iris, Twinkle Tray) also adjust gamma and can conflict with Night Light.

Method 1: Toggle Night Light off properly

The standard fix.

Open Settings → System → Display.
Find Night light. Toggle Off.
If screen still yellow: click Night light itself to enter detailed settings.
Click Turn off now at the top.
Disable Schedule night light.
Set Strength slider to 0% (just in case).
Return to Display settings, verify toggle is Off.
If still tinted: restart graphics driver. Press Win+Ctrl+Shift+B. Screen blinks. Tint should clear.

This solves most cases.

Method 2: Reset Night Light via registry

For stuck Night Light settings.

Open Registry Editor (Win+R, type regedit).
Navigate to: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\DefaultAccount\Cloud.
Find these two keys: $$windows.data.bluelightreduction.bluelightreductionstate and $$windows.data.bluelightreduction.settings.
Right-click each → Delete.
Close Registry Editor.
Sign out and back in (or restart Explorer via Task Manager).
Open Settings → System → Display. Night Light section is reset to defaults. Tint is gone.
Optional: re-enable Night Light with desired schedule. Setting will save fresh.

This fixes stuck registry state.

Method 3: Check for third-party color apps and ICC profile

For tints not caused by Night Light.

Check system tray (bottom right). Look for: f.lux, Iris, Twinkle Tray, SunsetScreen, or any blue-light filter.
Right-click each → Exit / Disable.
Check ICC color profile: Settings → Display → Color profile. Or Control Panel → Color Management → pick monitor → Profiles tab.
If a custom ICC profile is set (e.g., calibration result): switch to sRGB IEC61966-2.1 (default).
For laptops with built-in eye-care tools (Lenovo Vantage, Dell Display Manager, HP Audio Switch): open the vendor app and check for color/brightness mode settings.
For ASUS/MSI gaming laptops: their utility may have a “blue light filter” / “eye care” mode. Disable it.
For NVIDIA GPUs: NVIDIA Control Panel → Display → Adjust desktop color settings. Click Restore Defaults.
For Intel GPUs: Intel Graphics Command Center → Display → Color → reset to defaults.

This handles non-Night-Light causes.

How to verify the fix worked

Screen colors look neutral (whites are pure white, not yellow/cream).
Settings → Display → Night light shows Off.
No third-party color filter active in system tray.
Pure white test: open Notepad with default theme. Background should be true white #FFFFFF.

If none of these work

If yellow tint persists: Cable issue: HDMI/DisplayPort cable with damaged pin loses blue channel. Test different cable. Monitor settings: open the monitor’s on-screen menu (OSD). Reset color temperature to 6500K. Failing display: yellow tint that develops gradually may be a failing LCD/backlight. Test screen on second monitor — if external screen is normal, laptop screen is failing. Graphics driver: clean install via DDU + latest driver from GPU vendor. BIOS-level tint: some laptops have BIOS-level blue light filter. Check BIOS settings. For thermal causes: overheating GPU can shift colors briefly — usually cleared by cooling.

Bottom line: Toggle off Night Light, restart graphics driver (Win+Ctrl+Shift+B). For stuck state, delete registry keys under CloudStore\DefaultAccount\Cloud. Check for third-party color tools and ICC profile.
