How can I change the color of the SMF rows?

[RubberDucky]

The rows I am talking about are the <tr> ones. How can I change the color of these from the current light blue colors, to different shades of grey colors?

The .windowbg classes in ../Themes/default/css/index.css

Code Select Expand

.windowbg, #preview_body
{
   color: #000;
   background-color: #e7eaef;
}
.windowbg2
{
   color: #000;
   background-color: #f0f4f7;
}
.windowbg3
{
   color: #000;
   background-color: #cacdd3;
}
