Thank you so much for your reply–I actually figured it out (miracle), which was really rewarding. So amazing when the colors changed!
I wonder if there’s someone here who can help me–I can’t even figure our how to post a question! I have the exact same problem post-migration–my nice color scheme has been replaced by something that’s no good and that I can’t change. I am a total simpleton and have no idea about coding. Can I be helped, or should I just back out of wordpress.org and head back to wordpress.com?
