你可以使用滤镜:色调旋转(Ndeg)，但如果图像是黑白的，色调将永远不会改变。

但是，你可以把它和滤镜结合起来:sepia(100)。这将为图像添加色彩，色彩旋转滤镜可以改变。

Sepia增加了一个相当不饱和的颜色，所以增强一点滤镜:饱和(50);这使得它的颜色更深，色彩旋转可以更好地工作。

然后把它们组合在一起:

滤镜:棕褐色(100)饱和(50)色调旋转(280度)

然后尝试旋转的程度，直到你找到你喜欢的颜色。

如果你只需要一个图标，就不需要整个字体集，而且我觉得它作为一个单独的元素更“干净”。因此，出于这个目的，在HTML5中可以直接在文档流中放置SVG。然后你可以在你的.CSS样式表中定义一个类，并使用fill属性访问它的背景色:

工作小提琴: http://jsfiddle.net/qmsj0ez1/

请注意，在示例中，我使用:hover来说明行为;如果您只是想更改“正常”状态的颜色，则应该删除伪类。

你可以使用-webkit-filter和filter来使用过滤器: 过滤器对于浏览器来说相对较新，但根据以下CanIUse表:https://caniuse.com/#feat=css-filters，超过90%的浏览器支持过滤器

你可以将图像更改为灰度，深褐色和更多(请看示例)。

所以你现在可以用滤镜改变PNG文件的颜色。

为了字面上改变颜色，你可以使用-webkit-filter来合并CSS转换，当有事情发生时，你可以调用你选择的-webkit-filter。例如:

img {
    -webkit-filter:grayscale(0%);
    transition: -webkit-filter .3s linear;
    }
img:hover 
    {
    -webkit-filter:grayscale(75%);
    }

/* change image color to white */
filter: invert(100%) sepia(16%) saturate(7463%) hue-rotate(222deg) brightness(119%) contrast(115%);

/* change image color to red */`
filter: invert(16%) sepia(99%) saturate(7404%) hue-rotate(4deg) brightness(95%) contrast(118%);

/* change image color to green */
filter: invert(26%) sepia(89%) saturate(1583%) hue-rotate(95deg) brightness(96%) contrast(106%);

/* change image color to blue */
filter: invert(10%) sepia(90%) saturate(5268%) hue-rotate(245deg) brightness(109%) contrast(155%);
