How to save the QColor and then read it?

[ding]

I want to store the value of QColor,but I don't know how to store it and read it. I try to use QVariant ,but I failed.

I have solved the problem.

QString BottonColor;
QColor color = QColorDialog::getColor(Qt::black, this);
if (color.isValid())
{
BottonColor = color.name();
}
settings.SetBottonColor(BottonColor);

/// read it.

QString strColor = settings.GetFontColor();
QColor color;
color.setNamedColor(strColor);
