Car seat parts can be used to identify the type of car seat.
They can also be used for determining whether a car seat meets the safety criteria.
Car seat parts that have been tested by a qualified medical professional can be identified as having a medical issue by their color.
Color is often used as an indication of potential problems that may affect the health or safety of the passenger or other passengers.
