I'm not clear on whether you want to change the color of a QLabel
owned buy a QTabWidget, or you want to change the label (actually
QTab/QTabBar) of a QTabWidget (the part that makes it look like a
file folder). For the QLabel: it's a QWidget descendant, so it has
all of the QWidget methods for setting colors (see Qt QWidget docs
- foreground, background, etc). You can also overload the paint
method in a subclass.

To change the color of a single tab in a QTabBar, it looks like
you'd have to subclass QTabBar and overload the paint() method so
it knows what color each tab should be (paint() gets the index
number of the tab it's painting). Also look at the QTabWidget docs
for info about setting a new QTabBar.
