The simple answer to what I think you are asking is that you get a reference to the thing(s) you want to change and use it to call methods to make the changes. For example, in the demo app below, for class Blue to change the color of the colorPanel in class Red it needs a reference to class Red and uses this to call a method in Red to change the color. How you want to put things together (so they can communicate among themselves) is a matter of what works and what you're comfortable with. Trial and error and practice lead to success.
