Google Chrome is all dark

q: What happened to Google Chrome?  The address bar / omnibox is black instead of white and we do not have a theme installed.
a: Microsoft released Light and Dark mode for Windows 10 and Chrome is inheriting it. Click Start, type dark mode, click 'Color Settings' from the search results, scroll to the bottom. Look for 'Choose your default app mode' and it is most likely set to (X) Dark mode.  Click Light mode and Chrome will immediately switch back to white.
