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 */
}

是的:)

Surfin' Safari - Blog Archive » CSS Masks WebKit now supports alpha masks in CSS. Masks allow you to overlay the content of a box with a pattern that can be used to knock out portions of that box in the final display. In other words, you can clip to complex shapes based off the alpha of an image. [...] We have introduced new properties to provide Web designers with a lot of control over these masks and how they are applied. The new properties are analogous to the background and border-image properties that already exist. -webkit-mask (background) -webkit-mask-attachment (background-attachment) -webkit-mask-clip (background-clip) -webkit-mask-origin (background-origin) -webkit-mask-image (background-image) -webkit-mask-repeat (background-repeat) -webkit-mask-composite (background-composite) -webkit-mask-box-image (border-image)

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。

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

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%);
    }

试试这个:

 -webkit-filter: brightness(0) invert(1);
 filter: brightness(0) invert(1);
