Getting background color of a frame value in a Label

[Kayagni]

I am trying to get the red value of the background color of a frame, to put it into a label.
This color value has been set by a QColorDialog, and applied with QPalette.
There is no value in my label... What am I doing wrong?

Here's the code

void PatternEditor::on_boutonCouleurInit_clicked()
{
QColor couleur = QColorDialog::getColor(Qt::white, this); //sets couleur with QColorDialog

QPalette palette; 
palette.setColor(QPalette::Background, couleur); //sets background color
ui->initColorWidget->setAutoFillBackground(true); 
ui->initColorWidget->setPalette(palette); //apply color to the background's frame
ui->codeCouleurInitLabel->setText(QChar(couleur.red())); //(should) set text of my label with the red color value of couleur

}

Fixed... In fact, it was just a matter of QChar translation...
