    Description

      The documentation says that the colors are equal if they have the same RGB and
      alpha values (see: https://doc.qt.io/qt-5/qcolor.html#operator-eq-eq ).
      However, It appears that also the types of colors are checked. Like if two colors with different spec, but same RGB and same alpha values, == returns false. 

          QColor col1(255, 255, 255, 255);
    QColor colHSV = col1.toHsv();  // copy of the color above in a HSV format

    qDebug() << "RGBAs are equal - " << (col1.rgba() == colHSV.rgba());      // Return true
    qDebug() << "Names are equal - " << (col1.name() == colHSV.name());  // Return true
    qDebug() << "Colors are equal - " << (col1 == colHSV);                 // Return False

      Documentation should include this detail too.
