In your Activity you can tint your PNG image resources with a single colour:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    myColorTint();
    setContentView(R.layout.activity_main);
}

private void myColorTint() {
    int tint = Color.parseColor("#0000FF"); // R.color.blue;
    PorterDuff.Mode mode = PorterDuff.Mode.SRC_ATOP;
    // add your drawable resources you wish to tint to the drawables array...
    int drawables[] = { R.drawable.ic_action_edit, R.drawable.ic_action_refresh };
    for (int id : drawables) {
        Drawable icon = getResources().getDrawable(id);
        icon.setColorFilter(tint,mode);
    }
}

Now when you use the R.drawable.* it should be coloured with the desired tint. If you need additional colours then you should be able to .mutate() the drawable.
