[Support request] Customizing social links

I’m having trouble changing the colour of the social links under posts. I changed the colour of everything else to match my website, but the social links are just ignoring all attempts to change them. Strangely, I can change the colour of the links for when you hover over them, but not the colour for the normal link. Under the settings, I set the links to the correct colour, but the website continues to display the original. All other text/links changed colour just fine.

Is there another way of doing this?

Thank you.
