Actually when you insert <font...> you switch the label from plain text mode 
into rich text (html) mode. The change of color is more or less incidental.

Have a look at the palette() and setPalette(...) methods of QWidget (parent 
class of QLabel). You may also have to make the label background opaque.

Palette: http://developer.qt.nokia.com/doc/qt-4.8/qwidget.html#palette-prop

QPalette: http://developer.qt.nokia.com/doc/qt-4.8/qpalette.html (look for 
the setColor method...)

Background:

prop

I recommend you also go through more of the tutorials and examples...
