Display colours - need restoring

[pete2444]

Hello somehow I have changed my display settings. I think it MAY have been through Microsoft Teams but not sure. What has happed is that the background colour on everything has changed to orange. (I remember picking that colour) Even in this site I see the display below. I have tried restoring my computer to a past date and that didn't work. Can you please advise what to do (step by step please). Thanks Pete

Hi again the issue is something to do with colour settings. As you can see below the google banner is orange. I would just like instruction on restoring my computer to original colours please. It wasn't always like this.
