Convert RGB QColor to HSL

code:

QColor color = "#f0f0f0";
qDebug() << color;
qDebug() << color.toHsl();
qDebug() << color.convertTo(QColor::Hsl);

output:

QColor(ARGB 1, 0.941176, 0.941176, 0.941176)
QColor(AHSL 1, -1, 0, 0.941176) // hue == -1 here
QColor(AHSL 1, -1, 0, 0.941176) // hue == -1 here

from docs: QColor::fromHslF():

...

All the values must be in the range 0.0-1.0.

Docs for QML side color hsla():

Returns a color with the specified hue, saturation, lightness, and alpha components. All components should be in the range 0-1 (inclusive).

I need to get correct hue, saturation and lightness values on QML side. How to convert such RGB QColor to HSL QColor?
