Od tych buttonów masz arkusz buttons.css, a dokładnie to:
.post_buttons a, .popup_item_container a {
color: #738F9D !important;
padding: 2px 3px;
border-radius: 6px;
font-size: 11px;
margin: 0px;
font-weight: bold;
text-transform: uppercase;
-moz-box-shadow: 1px 1px 1px #666;
-webkit-box-shadow: 1px 1px 1px #666;
box-shadow: 1px 1px 1px #666;
text-shadow: rgba(0,0,0, .5) 0px -1px 0px;

Tylko nie wiem jak to się odbije na drugim selektorze, bo bez powodu tam nie jest, a nie chce mi się zakładać specjalnie konta, żeby to sprawdzać, więc najlepiej podmień to w ten sposób:
.popup_item_container a {
color: #738F9D !important;
padding: 2px 3px;
border-radius: 6px;
font-size: 11px;
margin: 0px;
font-weight: bold;
text-transform: uppercase;
-moz-box-shadow: 1px 1px 1px #666;
-webkit-box-shadow: 1px 1px 1px #666;
box-shadow: 1px 1px 1px #666;
text-shadow: rgba(0,0,0, .5) 0px -1px 0px;
background: rgb(33,49,71);
/* Old browsers */
background: -moz-linear-gradient(top, rgba(33,49,71,1) 0%, rgba(45,53,86,1) 40%, rgba(66,88,116,1) 100%);
/* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(33,49,71,1)), color-stop(40%,rgba(45,53,86,1)), color-stop(100%,rgba(66,88,116,1)));

I to jest już niepotrzebne, możesz usunąć:
.post_buttons a:hover {
-webkit-transition: color 0.3s linear;
-moz-transition: color 0.3s linear;
-o-transition: color 0.3s linear;
color: #fff !important;
}
