Note that "charge", when used without a qualifier, typically refers to the electric charge (which is the origin of the term). Color charge and weak charge are named "charge" only by analogy - there is no physical mechanism underlying all quantities named "charge" (though there is a mathematical definition of why a physical property can be considered a charge or not). Even mass itself can be viewed as a "charge" corresponding to the gravitational field.
