From Ruth:

Q: I have a blog – .blogspot,com
When I updated it for our South America and Antarctica I thought I was making the post title in yellow – but all the print is in yellow and hard to read. For the life of me I cannot figure out how to put it back to black.
Please help me when you can. My readers will thank you also

A: Yes, I’ve done that before! Here’s the fix:

• Select all the text
• Click the “Clear Formatting” tool. 
       Click the 3 dot menu at the right end of the tool bar
       Choose the last tool on that menu – Clear Formatting
       it looks like the image below
