it is possible to change or delete the shadow colour behind the fonts?


[EDIT]
i have found the solution. in STYLE.css

#gk-container .moduletable_color3>h3 { border-bottom:1px solid #fff; background:transparent url('../images/style1/module_titles.png') repeat-x; background-position:0 -45px; text-shadow:1px 1px 1px #000 }
