Following up on this post, I am writing to confirm what readers should be able to see with their own two eyes; the font is now black, and there is a new color for hyperlinks. Hopefully, readers will be pleased. Let me know what you think in comments.
Message received. No seriously, message received. Readers will note that I have made the font size noticeably bigger; when WordPress educates me on how to change the font color to black, I will do that as well. (And yes, I will also change the color of hyperlinks within texts of posts.)
