I have made this navigation-bar with **bootstrap** and I want to change its defaulted color(which is already black to something else). How could I do that with **CSS** style property??

```
<nav class="navbar navbar-inverse">
        <div class="container-fluid">
          <div class="navbar-header">
            <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>                        
            </button>
          </div>
    </nav>

```
