    This usually points to a contrast or theme setting being applied to some Microsoft apps rather than a general Windows bug.

    Try these checks:

    1. Check Teams theme
      • In Microsoft Teams, select Settings and more.
      • Select Settings > Appearance.
      • Under Theme, check whether High contrast is enabled.
      • If it is enabled, switch it back to the normal theme.
    2. Check Microsoft 365 app theme
      • In a Microsoft 365 app such as Outlook, go to File > Options > General.
      • In Office Theme, select Use system setting if the app should match Windows.
      • If the app is too bright or hard to read, Black is also available.
      • Select OK to apply.
    3. If the issue is mainly glare or low visibility
      • Microsoft documents that Teams can use a High contrast theme that affects Teams only.
      • Microsoft 365 apps can also use a separate Office Theme across apps.
      • Because of that, some Microsoft apps can look different from the Windows system theme.

    Based on the available information, this is not enough to confirm a Windows update bug. The behavior shown is consistent with app-specific theme or contrast settings being changed.

    Hi, good day!

    To help narrow down the cause

    Could you please confirm if this is only happening in Microsoft Edge?

    Have you installed any updates recently? If so, which one? When was the last time it worked properly?

    Have you tried the AI-suggested solutions?

    Confirm. When Edge version 154 landed the screen has a rose tinge. Outlook (new) based on WebView 2 changed the colors too. It has happened automatically after the update.

    Go to Settings > System > Display > Advanced display

    Do you see Color Profile in the resulting window?

    If so, find and switch "Automatically manage Color for apps" slider to ON for each Display (drop down at the top)
