Is there any way to change the sidebar link color w/o custom css or am I missing something? Currently it looks too light for me.
Right now there is no such an options for that but I might introduce it eventually.
You can change widget text color like this:
#secondary .widget a { /* Sidebar link color */
color: #111;
}
#secondary .widget { /* Regular sidebar sidebar text color */
color: #f00;
}
Add this code to Appearance >> Theme Options >> Other >> Custom CSS. Make sure to replace color codes with ones that you want to use.
