The colon ?

It has a number of uses. One of them is to make clear whom one is talking to, in cases where there are multiple people in a discussion, but a comment is intended for just one of them. In both of the above cases, B+b and I were indicating that we were talking to you, not to each other.

It can also be used in written dialogue, to show which character is speaking. Or to indicate that a list or example is about to follow. "There are three primary colours: red, yellow, and blue."
