QColorDialog provides some predefined colors to choose from, and also to save custom colors. However, when navigating between those colors, they are not announced by screen readers (tested with Orca on Linux and Narrator on Windows) or other assistive technology.

Steps to reproduce:

1. Build and run this sample program on Linux

   #include <QApplication>
   #include <QColorDialog>
   int main(int argc, char *argv[])
   {
       QApplication a(argc, argv);
       QColorDialog colorDialog;
       colorDialog.show();
       return a.exec();
   }
   

1. start the Orca screen reader
2. use the Tab key to navigate to the "Basic colors" section with predefined colors
3. use the arrow keys to navigate between the predefined colors

Actual result:

While navigating between predefined colors, the screen reader doesn't announce anything.

Expected result

The screen reader should announce the currently selected item/color.

Further information

When checking the accessibility tree with Accerciser, the predefined colors can also not be found in there.
