Using <QColorDialog>

Debug what? The selected colour is assigned to the "color" variable of yours.

I know, but I want to do some color manipulation and see the result

Well, you can always print the color to debug output:

#include <QtDebug>
...
qDebug() << color;

#include <QtDebug>
...
qDebug() << color;

To copy to clipboard, switch view to plain text mode 

Or you can fill a widget with the color so you can see it with your own eyes:

widget->setStyleSheet(QString("background: %1").arg(color.name()));

widget->setStyleSheet(QString("background: %1").arg(color.name()));
