hmmm - ugly coding in your template css..
lots..
loose -

.adminform button, #adminForm button, .button, button, a.readon, .pagenav-next a, .pagenav-prev a, input[type="submit"], input[type="button"], span.addtocart-button input.addtocart-button, .show_cart a, div.mobileSwitch > a {
background: url("../images/style1/btn.png") repeat-x scroll 0 bottom transparent;
border: 1px solid #D1D1D1;
color: #383838;
display: block;
float: left;
font-family: Arial,Verdana,sans-serif;
font-size: 11px;
font-weight: bold;
height: 26px !important;
line-height: 26px;
margin: 0;
padding: 0 8px;
}
#article-index ul li, div.pagination ul li, div#bottom-pagination ul li {
background: none repeat scroll 0 0 #FFFFFF;
color: #999999;
cursor: pointer;
display: inline-block;
font-size: 85%;
font-weight: bold;
overflow: hidden;
padding: 0;
}
#article-index ul li:hover, div.pagination ul li:hover, div#bottom-pagination ul li:hover {
background: none repeat scroll 0 0 #46660B;
border: 1px solid #577B15;
color: #FFFFFF !important;
}

#article-index ul li:hover, div.pagination ul li:hover, div#bottom-pagination ul li:hover {
background: none repeat scroll 0 0 #0098CA;
border: 1px solid #0079A1;
}
and a lot more - but you just have to methodically go thru with Firebug and find them and change them or rewrite some
often quicker to add css
e.g.
span.quantity-controls input.quantity-plus {
background: url("../images/Flexible/quantity_plus.png") no-repeat scroll 0 0 transparent;
border: 0 none;
border-radius: 0 4px 0 0;
box-shadow: 0 1px 1px #545454;
cursor: pointer;
float: left;
height: 16px;
margin: 0;
width: 16px;
}
etc - but there's no shortcuts... just find and change
