Why aren't you using parentheses when calling the changeColor() function ?
Considering the following line of code:
Why is he using
.change( changeColor ); //the function is called without parentheses
.change( changeColor() );
Can someone explain? I'm a little bit confused.

The function is not being called.
In this case, the function itself, and not the result of calling it, is being passed as a parameter to establish an event handler. It will be invoked later by the system when a change event occurs on range input element.
Functions used this way are often called callback functions.
