You should make an effort to describe the problem and analyse what each step of your code is doing (or not doing). Do this quite often leads to seeing your own mistake.

You are discarding the result of the function call at line 2. The value of 'text' at line 4 is the same as line 1.

QString pmsg;
pmsg = tr("<font color = red >Hello qt ..!!.\n"" </font size = 11 >");
ui->label->setText(pmsg);

above code will print the text in red colour

Yes. So?

If you are going to use HTML fragments to do rich text at least try to feed Qt valid HTML. What do you expect the attribute on the element end tag are going to do?
