If you have ever been frustrated because Dark Mode was somehow enabled on your computer here are a few possible solutions.1. I am on a Windows based device. If you go into your settings, then select personalization, colors, scroll down and choose your default app mode to be light.
2. It is possible you enabled a Chrome Flag (an experiment). It is worth a look. Go into chrome://flags/ and see what experiments have been enabled. The one you may have enabled is "Force Dark Mode for Web Contents". Simply select the blue enabled bar and choose to disable. Then, relaunch the Chrome browser.
