CSS - Add Color to Black & White Png Image Using a Filter

Change color of PNG image via CSS?

You can use filters with -webkit-filter and filter:
Filters are relatively new to browsers but supported in over 90% of browsers according to the following CanIUse table: https://caniuse.com/#feat=css-filters

You can change an image to grayscale, sepia and lot more (look at the example).

So you can now change the color of a PNG file with filters.

body {
    background-color:#03030a;
    min-width: 800px;
    min-height: 400px
}
img {
    width:20%;
    float:left; 
     margin:0;
}
/*Filter styles*/
.saturate { filter: saturate(3); }
.grayscale { filter: grayscale(100%); }
.contrast { filter: contrast(160%); }
.brightness { filter: brightness(0.25); }
.blur { filter: blur(3px); }
.invert { filter: invert(100%); }
.sepia { filter: sepia(100%); }
.huerotate { filter: hue-rotate(180deg); }
.rss.opacity { filter: opacity(50%); }

CSS - Add Color to Black & White PNG Image Using a Filter

You can do it with CSS filters, though I wouldn’t recommend that at all:

.colorizable {    filter:        /* for demonstration purposes; originals not entirely black */        contrast(1000%)        /* black to white */        invert(100%)        /* white to off-white */        sepia(100%)        /* off-white to yellow */        saturate(10000%)        /* do whatever you want with yellow */        hue-rotate(90deg);}
.example-clip {    display: block;    height: 20px;    margin: 1em;    object-fit: none;    object-position: 0 0;    width: 300px;}
.original {    filter: contrast(1000%);}
body {    background: #333;}

<img class="colorizable example-clip" src="https://cdn.sstatic.net/Sites/stackoverflow/img/wmd-buttons.svg" /><img class="original example-clip" src="https://cdn.sstatic.net/Sites/stackoverflow/img/wmd-buttons.svg" />

CSS filter: make color image with transparency white

You can use

filter: brightness(0) invert(1);

html {  background: red;}p {  float: left;  max-width: 50%;  text-align: center;}img {  display: block;  max-width: 100%;}.filter {  -webkit-filter: brightness(0) invert(1);  filter: brightness(0) invert(1);}

<p>  Original:  <img src="http://i.stack.imgur.com/jO8jP.gif" /></p><p>  Filter:  <img src="http://i.stack.imgur.com/jO8jP.gif" class="filter" /></p>

Is there any way to colorize a white PNG image with CSS only?

This can be done with css masking, though unfortunately browser support is really bad (I believe webkit only).

http://jsfiddle.net/uw1mu81k/1/

-webkit-mask-box-image: url(http://yourimagehere);

Because your image is all white, it is a perfect candidate for masking. The way the mask works is that wherever the image is white, the original element is shown as normal, where black (or transparent) the original element is not shown. Anything in the middle has some level of transparency.

EDIT:

You can also get this to work in FireFox with slight help from svg.

http://jsfiddle.net/uw1mu81k/4/

div {  width: 50px;  height: 50px;  mask: url(#mymask);  -webkit-mask-box-image: url(http://www.clker.com/cliparts/F/5/I/M/f/U/running-icon-white-on-transparent-background-md.png);}

<div style="background-color: red;"></div><div style="background-color: blue;"></div><div style="background-color: green;"></div><div style="background-color: orange;"></div><div style="background-color: purple;"></div>
<svg height="0" width="0">  <mask id="mymask">    <image id="img" xlink:href="http://www.clker.com/cliparts/F/5/I/M/f/U/running-icon-white-on-transparent-background-md.png" x="0" y="0" height="50px" width="50px" />  </mask></svg>

How to replace color of PNG image using CSS?

Your icon is a png image, so each pixel is defined separately to have its own color. There are no whole shapes that you can target with css and define a color, as you would for regular HTML elements.

However, there I a few things I would say:

I would have thought that it should be possible to change the color of this shape in photoshop without making it look any more grainy or pixelated than before.
I would suggest making this into an svg. This is a vector file format, so it generally has a smaller file size compared to pixel images, has completely sharp and defined edges, and can be scaled up to any size without reducing its quality. And, most importantly for you, it's very easy to change its color with CSS.
You could try using CSS filters to change the appearance of your png. Check out this stackoverflow question to see if it helps: Change color of PNG image via CSS?

As I've said, an svg would be my recommended option. I've created a code snippet below of what that would look like – you'll find your color #2a4f6c in the code, so just change that if you want the image to have a different color again..

Apply a filter with CSS to change colors of a picture

you can use filter hue-rotate(*x*deg) to change the colors, here I have attached code.

body {  align-items: center;  display: flex;  font-family: Helvetica, sans-serif;  height: 100vh;  justify-content: center;  margin: 0;}body div {  font-size: 15px;  margin-top: 15px;  text-align: center;}

How to make a color white using filter property in CSS

You can combine filter properties like this.

brightness(0) invert(1);

body {
  background-color: #dadada;
}

.custom-1 {
  filter: invert(0.5);
}

.custom-2 {
  filter:  brightness(0) invert(1);
}

<img src="https://s.cdpn.io/3/kiwi.svg" class="standard" width="50" height="50" alt="img">

<img src="https://s.cdpn.io/3/kiwi.svg" class="custom-1" width="50" height="50" alt="img">

<img src="https://s.cdpn.io/3/kiwi.svg" class="custom-2" width="50" height="50" alt="img">

Having Issue on Inverting Black to White PNG

I believe your issue is arising from using an image that is grey, rather than black. When this grey image is inverted, it just looks like a lighter color of grey.

Your code works fine, you just need to use a darker image to get the desired effect. Try swapping your image with this:

<img src="https://upload.wikimedia.org/wikipedia/commons/thumb/1/17/Yin_yang.svg/2000px-Yin_yang.svg.png" width="100px" height="100px">
