My website is http://www.prairiepariah.com
I am using the "Bueno" child theme and I'd like to change the color of the date circles (currently set to black). I want to make them magenta like the website title. I already checked here: http://en.forums.wordpress.com/topic/changing-the-colour-of-the-date-of-post-circle-for-bueno-1 and followed the instructions that some users provided like saving a PNG image and uploading it using the code provided but it didn't change anything. I also saved the circle image as a GIF and JPG just to see if that would work and it didn't. I'm not sure what I'm doing wrong and having a hard time altering this tiny detail.
Please help! I would really appreciate it.
