CSS for universally changing color of bold font

Help

Things I have tried

What I’m trying to do

I’d like to make it so that anytime font is bolded in the editor (and preview) it turns blue for example. Possible?

I have the custom CSS for the italics as follows:
i, em, span.cm-em {
color: #BB5606; }

What do I need to change to have one for the bold font too?

Might be worth checking this thread out and searching the forum since this has been asked before too.
