To turn off high contrast mode on Windows using keyboard shortcuts, press the Left Alt + Left Shift + Print Screen keys at once. You won’t see any pop-up window to confirm the action, but you will hear a “beep” sound before the system reverts to the default theme. You can use this shortcut again if you need to re-enable High Contrast mode.
On Android phones, you can turn off high contrast mode by selecting Settings > Ease of Access > High contrast from the Start button. Activate the toggle next to Turn on high contrast. Turn off the toggle next to “Turn on high contrast” to exit the high contrast mode.
I hope this helps!
