Bug report #17841
option to use live-updating color chooser dialogs is only partially implemented in QGIS 3 (i.e. only works from the top of the symbol tree)

1. with this option enabled in the settings, style a polygon layer with a "simple fill".
2. click in the symbol tree on "Simple fill", then click "Color" below to open the color chooser dialog. Click on a different color and the colors in the symbol tree and in the symbol preview area to the right will "live update".
3. click instead on "Fill" in the symbol tree, then open the color chooser dialog. Click on a color and the colors in the tree and the preview will not live update.
This doesn't seem terribly important, but it is a regression from 2.18
