Placing the SVG output directly inline with the page code I am able to simply modify fill colors with CSS like so:

Answer 1

Use the sepia filter along with hue-rotate, brightness, and saturation to create any color we want.

.colorize-pink {
  filter: brightness(0.5) sepia(1) hue-rotate(-70deg) saturate(5);
}

Answer 2

Late to the show here, BUT, I was able to add a fill color to the SVG polygon, if you're able to directly edit the SVG code, so for example the following svg renders red, instead of default black. I have not tested outside of Chrome though:

<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
 width="500px" height="500px" viewBox="0 0 500 500" enable-background="new 0 0 500 500" xml:space="preserve">
    <polygon 


        fill="red"


        fill-rule="evenodd" clip-rule="evenodd" points="452.5,233.85 452.5,264.55 110.15,264.2 250.05,390.3 229.3,413.35 
47.5,250.7 229.3,86.7 250.05,109.75 112.5,233.5 "/>
</svg>

 .icon { 
  width: 48px;
  height: 48px;
  display: inline-block;
  background: url(https://s3-us-west-2.amazonaws.com/s.cdpn.io/18515/heart.svg) no-repeat 50% 50%; 
  background-size: cover;
}

.icon-orange { 
  -webkit-filter: hue-rotate(40deg) saturate(0.5) brightness(390%) saturate(4); 
  filter: hue-rotate(40deg) saturate(0.5) brightness(390%) saturate(4); 
}

.icon-yellow {
  -webkit-filter: hue-rotate(70deg) saturate(100);
  filter: hue-rotate(70deg) saturate(100);
}

You can use CSS masks, With the 'mask' property, you create a mask that is applied to an element.

.icon {
    background-color: red;
    -webkit-mask-image: url(icon.svg);
    mask-image: url(icon.svg);
}
