Not really. The documentation says:

"""
Emitted when a color is activated from the color chooser. This usually happens
when the user clicks a color swatch, or a color is selected and the user presses
one of the keys Space, Shift+Space, Return or Enter.
"""

i.e. you need to activate the color, just like you'd activate a widget
or a menu item.

That seems confusing to me. The way its written (or rather, the way I'm reading it) implies the signal will be emitted on any color change ("activated"). However, using the "notify" signal seems to work as well, although the signal is emitted a few times on startup that I'll have to ignore.

Can you create a small, self-contained test case that reproduces the
behaviour you experience, so that we don't have to clone, build, and
run a whole application?

I through together a standalone Python3 script really quick, hopefully this works for you.
