I have just checked my 4.1.3 board and there is definitely a stylevar called vbcms_widget_color which I changed to a nice bright pink!

I then went into vbcms.css and changed the code to read this

.cms_widget_header h3 {
color: {vb:stylevar vbcms_widget_color};

Originally this

.cms_widget_header h3 {
color: {vb:stylevar sidebar_header_color};

The widget_header h3 is calling to any stylevar I insert into there which subsequently changes all the text to that color.

Try changing the stylevar to a known one that you dont use!

What I find confusing is that you cant locate the same stylevar I have but as I havent got a link to your forum or known skin I'm sorry to say I can be of no further assistance.
