I checked on that and found why it happens but I'm not sure if it's something that I can fix.

Basically the reason why the color change works in posts is because posts are considered a different "category" than the rest of the content on their respective pages. As such, all I really had to do was change the link color for the post "category" to what it is now.
In other words, the link color in posts used to be the same color as all of the other links on the forum (the navigation at the top, links on the main index, etc) which is black so to fix it I simply changed the link color for the post "category" which overrode the regular link color. Posts in the previous posts area under the reply form have no such "category" like the regular posts do and are considered just part of the page itself, so they use the general link color that everything else on the page is meant to use. If I change the color there, it will change the color of the links in the navigation and on the main index as well since they all fall under the same general color property.

I know a fix is definitely possible (and it's probably as simple as putting previous posts into their own "category" as well) but I don't really want to muck around with creating new "categories" for stuff and risk screwing things up.
(In before Petie and Kosheh laugh at how easy of a fix it is and do it in like 10 seconds)
