Changing text color of a button on other pages?

Looking to keep the text on the homepage button white but orange in the other pages.

Any CSS code out there for this?

The easiest way to do this would make the button text orange by default, then on the Homepage under this under Settings -> Advanced -> Page Header Code Injection

<style type="text/css">
.header-display .btn {
  color:white;
}
</style>

I am using this custom css code

//NAVIGATION BUTTON COLOR CHANGE

.Header-nav-item[href="/lets-eat"]{
    background: transparent !important;
    border: 2px solid #B98847 !important;
  color: #00000 !important;}

.Header-nav-item[href="/lets-eat"]:hover {
  color: #9D9995 !important;
}
