CHange font color for previously selected link in Menu

I’ve inherited a website that’s gone through several wordpress developers. We’ve changed the brand colors on the site, and I’m trying to root out the last remaining bit of the old color scheme in the menu. The holdout is the color of the last menu item clicked, once the user moves to hover over the next menu item. I can’t figure out the appropriate class.

Its the nav.bg-solid part of the menu that needs this edit, after you scroll down from the top a ways. the menu switches to a white background with teal text. Except when you move to another menu item, the kelly green suddenly appears.

Here’s what I’ve got ion my custom CSS that’s managed to switch everything except the holdout. The last two entries are the most rent attempts that got me nowhere.

nav .navbar-collapse .navbar-right > li > a, nav .navbar-collapse .navbar-right li.menu-item-has-children .dropdown-menu li a, .dropdown-menu>li>a {
  font-size: 20px;
  font-weight: 400;
}
nav .navbar-header .navbar-brand img {
  width: 200px;
}
.slider-caption .col-header-txt a {
  width: 300px;
}
nav.bg-solid .navbar-collapse .navbar-right > li.active > a {
border-bottom: 2px solid #3CAEA3;
}
nav.bg-solid {
color: #3CAEA3;
}
.sec-contact .contact .contact-info h5 {
color: #3CAEA3;
}
.main-navigation ul li:hover > a {
    color: #3CAEA3;
}
.nav-horizontal .current-menu-item a{
    color: #3CAEA3;
}
nav.bg-solid .navbar-collapse .navbar-right > .current-menu-item > a {
    color: #3CAEA3;
}
nav.bg-solid .navbar-collapse .navbar-right > li:hover > a {
    color: #3CAEA3;
}
nav.bg-solid .navbar-collapse .navbar-right > .current-menu-item > a {
border-bottom: 2px solid #3CAEA3;
}
nav.bg-solid .navbar-collapse .navbar-right > li:hover > a {
border-bottom: 2px solid #3CAEA3;
}
nav.bg-solid .navbar-collapse .navbar-right > a:visited {
    color: #3CAEA3;
}
nav.bg-solid .navbar-collapse .navbar-right > a {
    color: #3CAEA3;
}

Note that the theme has been edited/restructured using Unyson before I came on board.
