Families of embedded discrete finite state programs are modeled using input-enabled alternating transition systems. One model describes all functionality, while each variant is defined by an environment, describing its possible uses. The environments show both the inputs that a system can receive and indicate which of the system’s responses are relevant for the environment. The latter trait, called color-blindness, creates new possibilities for system transformations in the specialization process. We demonstrate the use of the framework by applying it to two classes of realistic design languages. An example of a product line of alarm clocks is used throughout the article.
