I'm open to suggestions as far as whether we should change the color, underline links, or both, but as it is it's a little too subtle for less than perfect monitors and viewing angles.

I've build a simple userstyle to use cause I was annoyed by it:
div.message a { color: #d1802a; } https://userstyles.org/styles/103649/make-links-identifiable
(One that also does the stars, and every other link in the star list because as far as I can tell there's no other way of telling:)
div.message a, #starred-posts a { color: #d1802a; } In addition to Kevin's answer, I hacked his snippets into a userstyle that changes the colors of both the stars' links and the rest of them, and also works on all SE sites instead of just GDSE. That part can be edited in the js file.
