Yes     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

Answering because I was looking for a solution for this   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   So  I figured a work around and thought it might help people if they too stumble here   So what I did is pretty much the same with three main differences    the url being in my img tag  I put it and a label  in another div on which   after will work  the  mix-blend-mode  is set at  difference  instead of  multiply  or  screen   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    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    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          https   codepen io spaceplant pen oZyMYG

I found this great codepen example that you insert your hex color value and it returns the needed filter to apply this color to png  CSS filter generator to convert from black to target hex color  for example i needed my png to have the following color  1a9790  then you have to apply the following filter to you png  filter  invert 48   sepia 13   saturate 3207   hue-rotate 130deg  brightness 95   contrast 80

I found this while googling  I found best working for me     HTML   lt div class  img  gt  lt  div gt    CSS   img     background-color  red    width  60px    height  60px     -webkit-mask-image  url  http   i stack imgur com gZvK4 png        http   jsfiddle net a63b0exm

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   img       -webkit-filter grayscale 0        transition  -webkit-filter  3s linear        img hover            -webkit-filter grayscale 75

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   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   Here s the snippet   x000D   x000D   lt svg xmlns  http   www w3 org 2000 svg  version  1 1  width  60  height  90  style  float left  gt  x000D     lt defs gt  x000D       lt filter id  colorMask1  gt  x000D         lt feFlood flood-color   ff0000  result  flood    gt  x000D         lt feComposite in  SourceGraphic  in2  flood  operator  arithmetic  k1  1  k2  0  k3  0  k4  0    gt  x000D       lt  filter gt  x000D     lt  defs gt  x000D     lt image width  100   height  100   xlink href  http   i stack imgur com OyP0g jpg  filter  url  colorMask1     gt  x000D   lt  svg gt  x000D   lt svg xmlns  http   www w3 org 2000 svg  version  1 1  width  60  height  90  style  float left  gt  x000D     lt defs gt  x000D       lt filter id  colorMask2  gt  x000D         lt feFlood flood-color   00ff00  result  flood    gt  x000D         lt feComposite in  SourceGraphic  in2  flood  operator  arithmetic  k1  1  k2  0  k3  0  k4  0    gt  x000D       lt  filter gt  x000D     lt  defs gt  x000D     lt image width  100   height  100   xlink href  http   i stack imgur com OyP0g jpg  filter  url  colorMask2     gt  x000D   lt  svg gt  x000D   lt svg xmlns  http   www w3 org 2000 svg  version  1 1  width  60  height  90  style  float left  gt  x000D     lt defs gt  x000D       lt filter id  colorMask3  gt  x000D         lt feFlood flood-color   0000ff  result  flood    gt  x000D         lt feComposite in  SourceGraphic  in2  flood  operator  arithmetic  k1  1  k2  0  k3  0  k4  0    gt  x000D       lt  filter gt  x000D     lt  defs gt  x000D     lt image width  100   height  100   xlink href  http   i stack imgur com OyP0g jpg  filter  url  colorMask3     gt  x000D   lt  svg gt  x000D   x000D   x000D

The simplest one line that worked for me   filter  opacity 0 5  drop-shadow 0 0 0 blue     You can adjust opacity from 0 to 1 to make color lighter or darker

The img tag has a background property just like any other  If you have a white PNG with a transparent shape  like a stencil  then you can do this    lt img src   stencil png  style   background-color  red  gt

I required a specific colour  so filter didn t work for me   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    x000D   x000D   colored-image   x000D          background-image  linear-gradient to right   BADA55   BADA55   url  https   i imgur com lYXT8R6 png    x000D          background-blend-mode  overlay  x000D          background-size  contain  x000D          width  200px  x000D          height  200px          x000D        x000D   lt div class  colored-image  gt  lt  div gt  x000D   x000D   x000D

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   With any white png  eg  white icon on transparent background   you can add an   after selector to recolor    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        See this codepen  applying the color swap on hover   http   codepen io chrscblls pen bwAXZO

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 fill property   Working fiddle  http   jsfiddle net qmsj0ez1   Note that  in the example  I ve used  hoverto illustrate the behaviour  if you just want to change color for the  normal  state  you should remove the pseudoclass

When changing a picture from black to white  or white to black the hue rotate filter does not work  because black and white are not technically colors   Instead  black and white color changes  from black to white or vice-versa  must be done with the invert filter property     img1     filter  invert 100

In most browsers  you can use filters     on both  lt img gt  elements and background images of other elements and set them either statically in your CSS  or dynamically using JavaScript   See demos below      lt img gt  elements  You can apply this technique to a  lt img gt  element     x000D   x000D   original   changed   x000D      width  45   x000D      padding  2 5   x000D      float  left  x000D    x000D   x000D   changed   x000D      -webkit-filter   hue-rotate 180deg   x000D      filter   hue-rotate 180deg   x000D    x000D   lt img id  original  src  http   i stack imgur com rfar2 jpg    gt  x000D   x000D   lt img id  changed  src  http   i stack imgur com rfar2 jpg    gt  x000D   x000D   x000D    Background images  You can apply this technique to a background image     x000D   x000D   original   changed   x000D      background  url  http   i stack imgur com kaKzj jpg    x000D      background-size  cover  x000D      width  30   x000D      margin  0 10  0 10   x000D      padding-bottom  28   x000D      float  left  x000D    x000D   x000D   changed   x000D      -webkit-filter   hue-rotate 180deg   x000D      filter   hue-rotate 180deg   x000D    x000D   lt div id  original  gt  lt  div gt  x000D   x000D   lt div id  changed  gt  lt  div gt  x000D   x000D   x000D    JavaScript  You can use JavaScript to set a filter at runtime     x000D   x000D  var element   document getElementById  changed    x000D  var filter    hue-rotate 120deg  saturate 2 4    x000D  element style  -webkit-filter     filter  x000D  element style  filter     filter  x000D   original   changed   x000D      margin  0 10   x000D      width  30   x000D      float  left  x000D      background  url  http   i stack imgur com 856IQ png    x000D      background-size  cover  x000D      padding-bottom  25   x000D    x000D   lt div id  original  gt  lt  div gt  x000D   x000D   lt div id  changed  gt  lt  div gt  x000D   x000D   x000D
