Change color of PNG image via CSS?

Question

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?

Answer 1

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%); }
