Question, do you mean the Realm/Help tabs for links in that first image or the Packs Online # link?

For the first image "Explore/Battle" links, you need to change the .veryblack hex code or add it if it's not in your palette already.

For the second image, that's the .veryblack a:link and .veryblack a:visited hex code.

For the code to change the Toast notifications background, that'll be the following:

.poll-body { background-color: #HEX !important; }

along with .tertiary for a bit of it.
