Hey there Chris Bunch,
Thanks for reaching out to Apple Support Communities. We understand there is an issue with the appearance of your Mac. We’ll be happy to help.
To verify, is the desktop image you’re using on your Mac having any affect on the appearance? If you change that to a lighter image, does this change any of the items that appear to be in Dark Mode?
If not, boot your Mac into safe mode and see if the issue continues there. “Safe mode can help you to determine whether an issue is caused by software that loads as your Mac starts up.” You can read how to do this here:
How to use safe mode on your Mac
You may also want to check the other settings that can affect the appearance, like Accent color which could change this as well. This article has more info:
Use a light or dark appearance on your Mac
Take care.
