Yet another approach is to use mask. You then change the background color of the masked element. This has the same effect as changing the fill attribute of the svg.

HTML:

CSS:

glyph {
    display: inline-block;
    width:  24px;
    height: 24px;
}

glyph.star {
  -webkit-mask: url(star.svg) no-repeat 100% 100%;
  mask: url(star.svg) no-repeat 100% 100%;
  -webkit-mask-size: cover;
  mask-size: cover;
  background-color: yellow;
}

glyph.heart {
  -webkit-mask: url(heart.svg) no-repeat 100% 100%;
  mask: url(heart.svg) no-repeat 100% 100%;
  -webkit-mask-size: cover;
  mask-size: cover;
  background-color: red;
}
