Link color doesn't change as specified

On the Network theme>Customization>Text Colours page, I have set the “choose your link colour” to red and the “choose your link hover colour” to blue.

As you can see from my site, SOME links are red, but some are still the default green — and some (like the “compare all blog packages” link in the center of the home page — are gray.

Please help getting ALL the links to change as specified.
