I just added a href tag to my font awesome icon, which alters its color like so:

enter image description here

Is there a way to remove this link color?

<a href="https://www.w3schools.com"><i class="fa fa-facebook"></i></a>

You can change the color for all .fa icons inside anchor tags

a .fa {
    color: black;
}
