    Hello,
    there are at least two ways to call pre-defined color with Qt: Qt::GlobalColor and QColorConstants. It seems redundant to me.

    Is there a reason to prefer one over the other?

      Qt::Color is the old 'version' and a plain enum so it can e.g. accidentally converted to an integer. This was fixed in QColorConstants.
