Apps Tinted Yellow - Windows Colour Profile

Symptom

Chrome, Edge and Teams are tinted yellow, while the rest of Windows looks normal.

Colour management. The Windows setting that lets Windows manage colour for apps had been switched off.

Settings > System > Display > (the display) > Colour profile. Turn back on the option that lets Windows automatically manage colour for apps.

Forcing the colour profile through chrome://flags and edge://flags. Teams stayed yellow, so this isn’t the real fix.
