下面引用了示例代码，试试Yandex的老Map，选择这个选项按钮：.ymaps-layers-pane-工作，但没有2.1。这是可取的，使它跨浏览器，在IE中不工作

div#map {
  filter: url("data:image/svg+xml;utf8,<svg xmlns=\'http://www.w3.org/2000/svg\'><filter id=\'grayscale\'><feColorMatrix type=\'matrix\' values=\'0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0 0 0 1 0\'/></filter></svg>#grayscale");
  /* Firefox 3.5+ */
  -webkit-filter: grayscale(100%);
  /* Chrome 19+ & Safari 6+ */
  filter: grayscale(100%);
  -webkit-filter: grayscale(100%);
  -moz-filter: grayscale(100%);
  -ms-filter: grayscale(100%);
  -o-filter: grayscale(100%);
  filter: url(desaturate.svg#greyscale);
  filter: gray;
}
