c++ - How to emit a signal with arguments in QT?

Question

  connect(ui->SetModelColor, &QPushButton::clicked, this, [this](){

    QColor color = QColorDialog::getColor(Qt::white, this, "Choose color");
    double Red = static_cast<double>(color.red());
    double Green = static_cast<double>(color.green());
    double Blue = static_cast<double>(color.blue());
    emit ModelRGBdata(Red, Green, Blue);
    });

I am emitting a signal(ModelRGBdata) from one class ,and I am capturing this signal inside another class code shown below

connect(mColorWidget, &ColorSelection::ModelRGBdata, this, [this](double Red, double Green, double Blue) {

    actor->GetProperty()->SetColor(Red, Green, Blue);

    });

But it throws an exception when the line emits gets executed.

What's the problem here ?
