Please tell me how to change it.

I changed this code but it did not work..

.mod_easyblognewpost a:link, .mod_easyblognewpost a:visited, .mod_easyblognewpost a:hover {
background: none repeat scroll 0% 0% rgb(78, 129, 186);→I changed background: none repeat scroll 0% 0% rgb(250, 119 ,137) !important;
}

Thank you for your help.
