Changing link color in footer with dark background:

I am using the Sterling theme. The footer background is dark blue. My links are normally dark blue. The text in the footer is white. However, when I put a link or email link in the footer, it turns dark blue. I’ve tried using code to change the color of the link in the footer to be white or lite yellow, but nothing seems to work. Can anyone help me? Thanks, Jerri - jerrilyne424@gmail.com
