Menu link colors

So I followed the instructions here: https://catchthemes.com/support-forum/topic/header-media-title-and-text-change-colors/ to change the color behind the menu. I changed it to a dark color, so want the links to be white. But there is now setting for changing just the menu colors to white, and all links on every page turn white, which is bad. Is there a way to change just the menu-links to white and leave all other links as they were? The site is blocked from public viewing at the moment and I have a child theme.
