How to customize the header display color?

Question

I'm new to jQuery mobile. I was trying to change the default header color to a #013A6F.

<div data-role="header" data-theme="b">
  <h1> Welcome</h1>
</div>

Any insight??

I think this would be your css.[Link here]
If so, do this.

.ui-bar-b h1{
    background-color: #013A6F;
}
