How to change menu font color

Hi, I changed my font menu color to white, which I was trying to only change for my home page, but it's now changed to white across the website which is a problem as the menu doesn't show up on the other pages with a white background. How can I change it back to black? This probably simple but I can't remember how I changed it to white font in the first place!

You can try this code below, however if you share. a link to your site we can check:

body.homepage .header-nav-wrapper a {
  color: white !important;
}
