Google and Chrome have made every device dark theme

[meebers 0]

I was trying out a dark theme on a fairly new installation of the Chrome browser on my new windows 11 computer. At first I could not get Chrome back to its default theme or any other light theme. After following extensive instructions a few times I used Revo to uninstall chrome. I reinstalled Chrome and it was still an unchangeable dark theme.It is not set to use the system theme which is dark.

I uninstalled with Revo again and then went through explorer with Everything and deleted all I could that was definitely Chrome related. I reinstalled and it was still dark.
I have now discovered with great horror that my Android phone is using a dark theme and my redmi tablet is also using a dark theme. This suggests to me that Google has taken on the idea that everything has to be a dark theme.

I'm at a total loss. I started this because I have low vision. However, the dark seems don't work for me and I can't get out of them on any device. I haven't checked my laptop yet but I'm sure the same is true there.
My Android devices are dark themed everywhere, not just in Chrome. This is why I am thinking it is a Google issue.
Greatly appreciate any ideas or suggestions because now I can't see any screen easily
Thanks
My computer specs are already listed on my profile and I have the machine packing up at the moment so please look there. I believe it's 24h
