Which ink color designates no-shows and cancellations in appointment scheduling?

In appointment scheduling, red ink is commonly used to signify no-shows and cancellations. This practice stems from the visibility and seriousness associated with the color red, which typically conveys warning or attention. By using red ink, medical practices can quickly identify appointments that were missed or canceled, allowing for better management of schedules and resources. This coding system helps staff easily recognize the need to follow up with patients regarding missed appointments or to fill those slots with other patients, thus improving efficiency in scheduling.
