It is very cool for questions like this that Qt is a sourcecode
distribution even if you use the binary installers. Use the force! Read
the Source!

Straight from the Qt source code....

QColor QPen::color() const
{
    return d->brush.color();
}

QBrush QPen::brush() const
{
    return d->brush;
}

Yes, thank you remembering me to learn more from the Source.

Or write a small test program:

QPen pen;
pen.setColor( Qt::red );
QBrush b;
b.setColor( Qt::blue );
pen.setBrush( b );
Q_ASSERT( pen.color() == pen.brush().color() );

(not tested)
