Selection colors have attached styles, I'd like to publish these styles but I don't know where they're coming from

So I selected some shapes and noticed the selection colors already had some attached styles, but these styles are not in my color styles.
Where are these styles coming from?! What kind of style can be attached to a color if it’s not a color style??

I DO want these colors to be in my color styles! It seems I have to detach their current style in order to add them to my local styles library. What’s going on?
I really don’t want to have to detach and add all these styles individually.
