Could you change color of comment bubble?

Since a recent update of either this plugin or WordPress, the numbers appear as a medium grey on a slightly darker grey background, making them very difficult to read.

I tried several different themes form my Admin page, but it had no effect on the murky color of the bubbles.

The numbers used to be easy enough to read. I would like the color to match the screenshot on the official WordPress plugins page, just as it used to be.
