Q:

Bootstrap - change color panel-primary

I have used panel-primary to make a panel in Bootstrap. But now I want to change the default blue color. 
I have added the css, but with this change the panel keeps the blue color
#panel-primary {
background-color: #194719;

}
How can I change this blue color?

A:

panel-primary is a class.
You will need to do it like this:
.panel-primary {
     background-color: #194719 !important;
}

Replace the # before panel-primary with a . (leave the # on the colour as is)
The # is used when you reference an element ID in CSS. A . will reference a class.
