Grouping illustrations for coloring by the type of creature depicted is a common method of organization. Examples include classifications such as domesticated animals (cats, dogs, horses), wildlife of specific regions (African savanna, North American forests), or aquatic life (fish, marine mammals, crustaceans). This method provides a structured way to browse and select images based on preferred fauna.
Sorting options based on the living things portrayed streamlines the selection process for individuals seeking particular subjects. This approach to categorization is beneficial in educational settings, allowing educators to easily locate species-specific materials for learning activities. Historically, this method mirrors traditional biological classification systems, making it intuitive for users.
