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

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.
