Colour of the tag not changing

[ranganatha2g]

I'm trying to change colour of the tag if the tag is clicked.
I'm doing this is onTagClickListener, code can be found below:

private OnTagClickListener onTagClickListener = new OnTagClickListener() {
@OverRide
public void onTagClick(Tag tag, int i) {
tag.tagTextColor = getContext().getColor(R.color.black);
}
};

Is it possible to change colour of the tag this way?
Also, I need to change colour of the tag depending on the present colour of the tag. Is it possible to do using this library?
Thanks.
