wxMac: wxTreeCtrl / wxTreeBook highlight color is not great (Issue #24605)
Jon Evans
Description
The selected-item highlight color used in wxTreeCtrl and wxTreeBook is very low-contrast with the text in both light and dark modes on wxMac. Screenshots from treectrl sample:

I have the same issue here on macOS 14.5
I think the gray color that you are seeing is the unfocused color.
When selected and the control has focus, tree or list controls should be drawn with the system focus color, like blue in my case, which works fine in wxWidget 3.2.4:

But since wxWidgets 3.2.5, at least wxListCtrl and wxTreeCtrl (and wxGenericDirCtrl using it) always show their selection in gray, so it is difficult to see which control (if you use multiple) currently has focus.
If the control looses focus, the selected items are drawn correctly in gray in both wxWidgets 3.2.4 and 3.2.5
Furthermore in the identically build listctrl.app and treectrl.app it seems keyboard interception is lost, only a short beep is sound when you press a key in 3.2.5. In wxWidgets 3.2.4 (see screenshot above) you will see keyboard notifications in the message pane as expected...
I also tested latest git snapshot today and the problems are both present.
It seems something focus colour & keyboard message handling is broken, at least for list and tree controls (text controls appear Ok) on Mac...
