Twitter bootstrap 如何获得比例灰色？

以下是我的一些清单：

      $gray-base:          #000 !default;
      $gray-darker:        lighten($gray-base, 13.5%) !default; // #222                    
      $gray:               lighten($gray-base, 46.7%) !default; // #777
      $gray-light:         lighten($gray-base, 65%) !default;   // #a6a6a6
      $gray-lighter:       lighten($gray-base, 93.5%) !default; // #eee

但是我想把#dddddddd做成与其他颜色一样的比例样式。这是怎么做到的。谢谢

$gray-medium:        lighten($gray-base, 86.5%) !default; // #dddddd  

您可以在此处进行测试：

HTML:

在源CSS窗口中，您应该看到：

.grayMedium {
    background: #dddddd;
}

不，我要求添加，dddddd，dddd，dddd，dddd，dddd，dddddd，dddd，dddddd，dddd，dddd，dddddd，dddddd，dddddd，dddddd，dddddd，dddddd，dddddd，dddd，dddddd，dddddd，dddddddd，dddddddddddddd，dddddddddddddddd，dddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd？

@gray-base:          #000;
@gray-medium:        lighten(@gray-base, 86.5%);

.grayMedium{
    background: @gray-medium;
}

.grayMedium {
    background: #dddddd;
}
