There are two main color conventions when it comes to how words are organized into alternative communication systems: The Modified Fitzgerald Key and the Goossens,’ Crain, and Elder. When we color code the communication systems, we allow users to find these words more easily within the screen. Regardless on which convention you decide to use, it would be important to remain consistent as the users progress or even as you switch between devices or communication support systems. Check out the infographics we designed. Feel free to save and share.
