It looks like a regression from a recent change.

All that is likely missing is a minimal example:

#include <QtWidgets/QApplication>
#include <QtWidgets/QColorDialog>
#include <QtCore/QDebug>

int main(int argc, char *argv[]) {
    QApplication app(argc, argv);

    // Opens the color dialog with black as the initial color.
    // Note that the HTML value and the corresponding color display
    // do not change while the mouse button is held down and moved
    // within the color field.
    QColor selectedColor = QColorDialog::getColor(Qt::black, nullptr, "Select color");

    if (selectedColor.isValid()) {
        qDebug() << "Selected color:" << selectedColor.name();
    } else {
        qDebug() << "Selection cancelled.";
    }

    return 0;
}

Perhaps someone with sufficient permissions can use this—along with the details provided by @markjamescapella—to open a ticket in the bug reporting system.

I am requesting a minimal example to ensure everybody works from the same start.

Since you reproduced the same issue, can you open a ticket on the bug report system providing that minimal sample and indications ?

@markjamescapella has demonstrated the error in the second link (https://www.dropbox.com/scl/fi/upl1g7w8mofoli1ew1y1g/QT6bug.mkv?rlkey=u04njublm9si74hptnp3h4y34&st=qxc081uz&dl=0).
The error mentioned also occurs in my applications using this dialog (VS2026 C++17, QT 6.11.00).

That is pretty strange... Can you try again ?
Do you have a minimal buildable reproducer that shows your issue ?

I tried to use a duckduck account and that doesnt work either (I don't prefer a gmail account) so perhaps I'll drop the bug quick:

ColorPicker "Crosshairs" don't reflect color on drag when BLACK due to isNull() regression here:
