Hi Sean,
You need to customize css override for these, can you try css below and see (unfortunately all the classes was different where you need to target each dropdown to change the background color):
[setting dropdown]
[gist type="php"]
#es.mod-es.mod-es-toolbar .es-toolbar .es-toolbar-profile, #es.mod-es.mod-es-toolbar .es-toolbar .es-toolbar-dropdown-nav, #es.mod-es.mod-es-toolbar .es-toolbar .es-toolbar-dropdown-nav__item{
background-color: #345c34 !important;
}
[/gist]
[search background]
[gist type="php"]
#es.mod-es.mod-es-toolbar .es-toolbar__search-dropdown, #es.mod-es.mod-es-toolbar .es-toolbar__search .btn-toolbar-search, #es.mod-es.mod-es-toolbar .es-toolbar__search-filter-toggle, #es.mod-es.mod-es-toolbar .es-toolbar__search-input, #es.mod-es.mod-es-toolbar .es-toolbar__item--search {
background-color: #345c34 !important;
}
[/gist]
[notification background]
[gist type="php"]
body #es .es-albums .content-hint, body #es .o-empty, body #es.mod-es-logbox .es-login-box__form, body #es .es-story, body #es.popbox, body #es.popbox-navbar-profile .popbox-dropdown__hd, body #es.popbox-navbar-profile .popbox-dropdown__bd, body #es.popbox-navbar-profile .popbox-dropdown__ft, body #es.popbox-navbar-signin .popbox-dropdown__hd, body #es.popbox-navbar-signin .popbox-dropdown__bd, body #es.popbox-navbar-signin .popbox-dropdown__ft, body #es .popbox-dropdown-signin, body #es .popbox-dropdown, body #es .popbox-dropdown-nav__item.is-unread, body #es .popbox-dropdown-nav__item {
background-color: #345c34;
}
[/gist]
[conversation & friend background]
[gist type="php"]
body #es .es-albums .content-hint, body #es .o-empty, body #es.mod-es-logbox .es-login-box__form, body #es .es-story, body #es.popbox, body #es.popbox-navbar-profile .popbox-dropdown__hd, body #es.popbox-navbar-profile .popbox-dropdown__bd, body #es.popbox-navbar-profile .popbox-dropdown__ft, body #es.popbox-navbar-signin .popbox-dropdown__hd, body #es.popbox-navbar-signin .popbox-dropdown__bd, body #es.popbox-navbar-signin .popbox-dropdown__ft, body #es .popbox-dropdown-signin, body #es .popbox-dropdown, body #es .popbox-dropdown-nav__item.is-unread, body #es .popbox-dropdown-nav__item {
background-color: #345c34;
}
#es .popbox-dropdown__bd {
background-color: #345c34;
}
body.lightmode #es.popbox .o-empty, body.lightmode #es.popbox.popbox--navbar {
background-color: #345c34;
}
#es .popbox-dropdown-nav {
background-color: #345c34;
}
[/gist]
For link color it basically fall back using template link color setting

For title of the notification you can apply the css below:
[gist type="php"]
body #es .popbox-dropdown-nav__post {
color: 345c34;
}
[/gist]
For time posting you can use the css:
[gist type="php"]
#es .popbox-dropdown-nav__meta-lists {
color: #0372d5;
}
[/gist]
For content of notification you can use example css below:
[gist type="php"]
#es .popbox-dropdown-nav__link {
color: red;
}
[/gist]
Hope this helps
