I don't see an obvious issue with your code, I usually use CSS
classes personally and I know that works fine because I use
this technique all over terminix. I would suggest using the
GTK Inspector to debug the CSS issue, it's an awesome tool for
figuring out GTK CSS issues as it let's you change CSS on the
fly, see what CSS is being applied to an object, etc. You can
see how to use it at the link below:

Do you know if this works on windows?
No idea, I don't use Windows.
Personally I just add and remove classes as needed:
getStyleContext().addClass()
getStyleContext().removeClass()
So you basically have to create 2 classes? And what would you
do if you would have to change the color randomly (for a simon
says game)? I still think it is a bad idea to claim the way
with function calls as deprecated but introducing a new system
which is not as flexible (but maybe more powerfull).
C# with Visual Studio does it, PyQT does it: Function calls.
It can be done fine with on the fly changes, i.e. random colors,
it's somewhat more work then just calling a simple function call
but CSS gives you a lot more power as well. I do this in Terminix
where for certain themes I want to set the scrollbar background
to be the same color as the terminal background.
Essentially, add a class to the widget and then construct the CSS
for the class with your random background color as a string.
Create a CSSProvider and use loadFromData, same as captaindet's
example, to load the CSS in the string. Finally, use the widget's
style context to add the CSS provider which you just constructed.
If you want to change the color, remove that provider and add a
new one.
