这样做的一种方法很棘手但是有效

<强> HTML：

<div class="navbar navbar-default">
  <div class="container">
  <div class="navbar-header">
    <a class="navbar-brand" href="#">Brand</a>
  </div>
   <ul class="nav navbar-nav">
      <li><a href="#">Home</a></li>
      <li><a href="#">Link</a></li>
      <li><a href="#">Link</a></li>
      <li class="divider-vertical"></li>
      <li><a href="#">More</a></li>
  <li><a href="#">Options</a></li>
  </ul>
  </div>
</div>

<强> CSS：

.navbar-header{
    background:#e7e7e7;;
  position:relative;
}

.navbar-header:before {
    position: absolute;
    height: 100%;
    display: inline-block;
    background: #e7e7e7;;
    top: 0;
    left: -9999px;
    right: 100%;
}
.navbar-default{
    background:blue;
}

也许你可以使用只有两种颜色的“锐利”渐变作为背景颜色（使用http://www.colorzilla.com/gradient-editor/）我在这里复制了bootstrap文档中的标准navbar示例：

.navbar{
background: rgb(255,255,255); /* Old browsers */
background: -moz-linear-gradient(left,  rgb(255,255,255) 0%, rgb(255,255,255) 20%, rgb(125,185,232) 20%); /* FF3.6-15 */
background: -webkit-linear-gradient(left,  rgb(255,255,255) 0%,rgb(255,255,255) 20%,rgb(125,185,232) 20%); /* Chrome10-25,Safari5.1-6 */
background: linear-gradient(to right,  rgb(255,255,255) 0%,rgb(255,255,255) 20%,rgb(125,185,232) 20%); /* W3C, IE10+, FF16+, Chrome26+, Opera12+, Safari7+ */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#ffffff', endColorstr='#7db9e8',GradientType=1 ); /* IE6-9 */

}
