<p>for example i needed my png to have the following color <strong>#1a9790</strong></p>

<p>then you have to apply the following filter to you png</p>

<pre><code>filter: invert(48%) sepia(13%) saturate(3207%) hue-rotate(130deg) brightness(95%) contrast(80%);

<p>You might want to take a look at Icon fonts. <a href="http://css-tricks.com/examples/IconFont/">http://css-tricks.com/examples/IconFont/</a></p>

<p>EDIT: I'm using <a href="http://fortawesome.github.io/Font-Awesome/">Font-Awesome</a> on my latest project. You can even bootstrap it. Simply put this in your <code>&lt;head&gt;</code>:</p>

<pre><code>&lt;link href="//netdna.bootstrapcdn.com/font-awesome/3.2.1/css/font-awesome.min.css" rel="stylesheet"&gt;

&lt;!-- And if you want to support IE7, add this aswell --&gt;
&lt;link href="//netdna.bootstrapcdn.com/font-awesome/3.2.1/css/font-awesome-ie7.min.css" rel="stylesheet"&gt;
</code></pre>

<p>And then go ahead and add some icon-links like this:</p>

<pre><code>&lt;a class="icon-thumbs-up"&gt;&lt;/a&gt;
</code></pre>

<p>Here's the <a href="http://fortawesome.github.io/Font-Awesome/cheatsheet/">full cheat sheet</a></p>

<p>--edit--</p>

<p>Font-Awesome uses different class names in the new version, probably because this makes the CSS files drastically smaller, and to avoid ambiguous css classes.
So now you should use:</p>

<pre><code>&lt;a class="fa fa-thumbs-up"&gt;&lt;/a&gt;
</code></pre>

<p>EDIT 2:</p>

<p>Just found out github also uses its own icon font: <a href="https://octicons.github.com/">Octicons</a>
It's free to download. They also have some tips on <a href="https://github.com/blog/1135-the-making-of-octicons">how to create your very own icon fonts</a>.</p>

blocks|key|2445798|text|我已经能够使用SVG过滤器做到这一点。您可以编写一个滤镜，将源图像的颜色与要更改为的颜色相乘。在下面的代码片段中，泛色是我们想要将图像颜色更改为的颜色(在本例中为红色。)feComposite告诉滤镜我们是如何处理颜色的。算术的feComposite的公式是(k1*+i1+*i2+%2B+k2*i1+%2B+k3*i2+%2B+k4)，其中i1和i2相应地是in/in2的输入颜色。因此，只指定k1=1意味着它将只执行i1*i2，这意味着将两个输入颜色相乘。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|2445799|注意:这只适用于HTML5，因为它使用的是内联SVG。但我认为，通过将SVG放在一个单独的文件中，您也许能够在较旧的浏览器上使用此功能。我还没有尝试过这种方法。|2445800|下面是代码片段：|2445801|<svg+xmlns="http://www.w3.org/2000/svg"+version="1.1"+width="60"+height="90"+style="float:left">

<p>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, <strong>flood-color</strong> 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.</p>

<p>Note: This only works with HTML5 since this is using inline SVG. But I think you might be able to make this work with older browser by putting SVG in a separate file. I haven't tried that approach yet.</p>

<p>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.<br />
[...]<br />
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.</p>
<pre><code>-webkit-mask (background)
-webkit-mask-attachment (background-attachment)
-webkit-mask-clip (background-clip)
-webkit-mask-origin (background-origin)
-webkit-mask-image (background-image)

<p>Think I have a solution for this that's a) exactly what you were looking for 5 years ago, and b) is a bit simpler than the other code options here.</p>

<p>With any white png (eg, white icon on transparent background), you can add an ::after selector to recolor.</p>

<pre><code>.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 */
}
</code></pre>

<p>I required a specific colour, so filter didn't work for me.</p>

<p>Instead, I created a div, exploiting CSS multiple background images and the linear-gradient function (which creates an image itself). If you use the overlay blend mode, your actual image will be blended with the generated "gradient" image containing your desired colour (here, #BADA55)</p>

<p>Answering because I was looking for a solution for this.</p>

<p>the pen in @chrscblls answer works well if you have a white or black background, but mine wasn't. Aslo, the images were generated with ng-repeat, so I couldn't have their url in my css AND you can't use ::after on img tags.</p>

<p>So, I figured a work around and thought it might help people if they too stumble here.</p>

<p>So what I did is pretty much the same with three main differences:</p>

<ul>
<li>the url being in my img tag, I put it(and a label) in another div on which ::after will work.</li>
<li>the 'mix-blend-mode' is set at 'difference' instead of 'multiply' or 'screen'.</li>
<li>I added a ::before with exactly the same value so the ::after would do the 'difference' of the 'difference' made by the ::before and cancelled it-self.</li>
</ul>

<p>To change it from black to white or white to black the background color need to be white. 
From black to colors, you can choose whatever color.
From white to colors tho, you'll need to choose the opposite color of the one you want.</p>

<pre><code>.divClass{
   position: relative;
   width: 100%;
   height: 100%;
   text-align: left;
}
.divClass:hover::after, .divClass:hover::before{
   position: absolute;
   width: 100%;
   height: 100%;
   background: #FFF;
   mix-blend-mode: difference;
   content: "";
}
</code></pre>

<p>Use this great codepen example that you insert your hex color value and it returns the needed filter to apply this color to png</p>
<p>CSS filter generator to convert from black to target hex color</p>
<p>for example i needed my png to have the following color #EF8C57</p>
<p>then you have to apply the following filter to you png
Result:</p>
<pre><code>filter: invert(76%) sepia(30%) saturate(3461%) hue-rotate(321deg) brightness(98%) contrast(91%);

blocks|key|4061202|text|如果你只需要一个图标，那么就没有必要设置整个字体，而且我觉得作为一个单独的元素，它更“干净”。因此，在HTML5中，您可以将SVG直接放在文档流中。然后，您可以在.CSS样式表中定义一个类，并使用fill属性访问其背景颜色：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4061203|工作小提琴：http://jsfiddle.net/qmsj0ez1/|4061204|请注意，在示例中，我使用了:hover来说明行为；如果您只想更改“正常”状态的颜色，则应该删除伪类。|4061205|entityMap|0|LINK|mutability|MUTABLE|url|http://jsfiddle.net/qmsj0ez1/^0|2Q|4|0|6|T|0|0|D|6|0^^$0|@$1|2|3|4|5|6|7|R|8|@$9|S|A|T|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|U|8|@]|D|@$9|V|A|W|1|X]]|E|$]]|$1|H|3|I|5|6|7|Y|8|@$9|Z|A|10|B|C]]|D|@]|E|$]]|$1|J|3|-4|5|6|7|11|8|@]|D|@]|E|$]]]|K|$L|$5|M|N|O|E|$P|Q]]]]

<p>There's no need for a whole font set if you only need one icon, plus I feel it being more "clean" as an individual element. So, for this purpose, in HTML5 you can place a SVG directly inside the document flow. Then you can define a class in your .CSS stylesheet and access its background color with the <code>fill</code> property:</p>

<p>Working fiddle:
<a href="http://jsfiddle.net/qmsj0ez1/" rel="nofollow">http://jsfiddle.net/qmsj0ez1/</a></p>

<p>Note that, in the example, I've used <code>:hover</code>to illustrate the behaviour; if you just want to change color for the "normal" state, you should remove the pseudoclass.</p>


blocks|key|4061264|text|要真正改变颜色，您可以将CSS转换与-webkit-filter结合在一起，当发生某些事情时，您可以调用您选择的-webkit-filter。例如：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4061265|img+{
++++-webkit-filter:grayscale(0%25);
++++transition:+-webkit-filter+.3s+linear;
++++}
img:hover+
++++{
++++-webkit-filter:grayscale(75%25);
++++}|code-block|syntax|javascript|4061266|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

<p>To literally change the color, you could incorporate a CSS transition with a -webkit-filter where when something happens you would invoke the -webkit-filter of your choice. For example:</p>

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

<p>The solution that worked for me was using <code>filter: drop-shadow</code></p>
<p>filter: drop-shadow works differently than regular <code>box-shadow</code>.</p>
<p><code>filter</code> one applies shadow to real shape (so it supports transparent images).</p>
<p>The trick now is to 'hide' real image and show only the shadow.</p>

<p>Note that my use case is modifying icons colors into one, solid color, so this approach works for me, but might not for other use cases</p>


<p>Given a transparent PNG displaying a simple shape in white, is it possible to somehow change the color of this through CSS? Some kind of overlay or what not?</p>
