I've been able to do this using SVG filter. You can write a filter that multiplies the color of source image with the color you want to change to. In the code snippet below, flood-color is the color we want to change image color to (which is Red in this case.) feComposite tells the filter how we're processing the color. The formula for feComposite with arithmetic is (k1*i1*i2 + k2*i1 + k3*i2 + k4) where i1 and i2 are input colors for in/in2 accordingly. So specifying only k1=1 means it will do just i1*i2, which means multiplying both input colors together.

注意:这只适用于HTML5，因为它使用内联SVG。但我认为，通过将SVG放在一个单独的文件中，您可能能够在较老的浏览器中实现这一点。我还没有尝试过这种方法。

Here's the snippet: <svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="60" height="90" style="float:left"> <defs> <filter id="colorMask1"> <feFlood flood-color="#ff0000" result="flood" /> <feComposite in="SourceGraphic" in2="flood" operator="arithmetic" k1="1" k2="0" k3="0" k4="0" /> </filter> </defs> <image width="100%" height="100%" xlink:href="http://i.stack.imgur.com/OyP0g.jpg" filter="url(#colorMask1)" /> </svg> <svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="60" height="90" style="float:left"> <defs> <filter id="colorMask2"> <feFlood flood-color="#00ff00" result="flood" /> <feComposite in="SourceGraphic" in2="flood" operator="arithmetic" k1="1" k2="0" k3="0" k4="0" /> </filter> </defs> <image width="100%" height="100%" xlink:href="http://i.stack.imgur.com/OyP0g.jpg" filter="url(#colorMask2)" /> </svg> <svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="60" height="90" style="float:left"> <defs> <filter id="colorMask3"> <feFlood flood-color="#0000ff" result="flood" /> <feComposite in="SourceGraphic" in2="flood" operator="arithmetic" k1="1" k2="0" k3="0" k4="0" /> </filter> </defs> <image width="100%" height="100%" xlink:href="http://i.stack.imgur.com/OyP0g.jpg" filter="url(#colorMask3)" /> </svg>

在大多数浏览器中，你可以使用过滤器:

在<img>元素和其他元素的背景图像上 并在CSS中静态设置它们，或者使用JavaScript动态设置它们

请看下面的演示。

< img >元素

你可以把这个技巧应用到<img>元素上:

#original， #changed { 宽度:45%; 填充:2.5%; 浮:左; ｝ #{改变 -webkit-filter:色调旋转(180度); 滤镜:色调旋转(180度); ｝ <img id="original" src="http://i.stack.imgur.com/rfar2.jpg" /> <img id="changed" src="http://i.stack.imgur.com/rfar2.jpg" />

背景图片

你可以把这个技巧应用到背景图像上:

#original， #changed { 背景:url (http://i.stack.imgur.com/kaKzj.jpg); background-size:封面; 宽度:30%; 利润率:0 10% 0 10%; padding-bottom: 28%; 浮:左; ｝ #{改变 -webkit-filter:色调旋转(180度); 滤镜:色调旋转(180度); ｝ < div id = "原始" > < / div > < div id = "改变" > < / div >

JavaScript

你可以使用JavaScript在运行时设置一个过滤器:

var element = document.getElementById("changed"); Var过滤器= '色调-旋转(120度)饱和(2.4)'; 元素。Style ['-webkit-filter'] = filter; 元素。Style ['filter'] = filter; #original， #changed { 利润率:0 10%; 宽度:30%; 浮:左; 背景:url (http://i.stack.imgur.com/856IQ.png); background-size:封面; padding-bottom: 25%; ｝ < div id = "原始" > < / div > < div id = "改变" > < / div >

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。

源

我想我有一个解决方案，这是a)正是你在5年前寻找的，b)比这里的其他代码选项更简单一点。

对于任何白色png(例如，透明背景上的白色图标)，您可以添加::after选择器来重新上色。

.icon {
    background: url(img/icon.png); /* Your icon */
    position: relative; /* Allows an absolute positioned psuedo element */
}

.icon::after{
    position: absolute; /* Positions psuedo element relative to .icon */
    width: 100%; /* Same dimensions as .icon */
    height: 100%;
    content: ""; /* Allows psuedo element to show */
    background: #EC008C; /* The color you want the icon to change to */
    mix-blend-mode: multiply; /* Only apply color on top of white, use screen if icon is black */
}

查看代码依赖(在悬停上应用颜色交换):http://codepen.io/chrscblls/pen/bwAXZO

/* 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%);

我在谷歌上找到了这个，我发现最适合我的工作…
