Nevermind I figured out what I wanted to do.

The color comes from the hovered link style. It's actually a text-underline not a border. a.like-this:hover {color:;}

That did not change the color of it for me, with or without hover, and at . It continues to be red, even with an !important tagged onto it to get it noticed.

Which pet page are you working on?

I managed to figure it out on my own, but thank you for your help!

(Apparently, having .heart and your coding at the same time interferes with each other. And it wasn't the borders I needed to manipulate, it was text-shadow.)
