What type of messages are displayed in BLUE during scheduling?

The correct response identifies that blue messages during scheduling serve as informative messages. These messages provide users with essential information or context related to the scheduling process, helping to clarify details or give insights without implying any immediate action required. The use of blue helps differentiate these messages from others, making it clear to users that they are receiving helpful information as opposed to alerts or warnings.

In a scheduling system, it's crucial to provide different types of feedback to users, and informative messages in blue allow for a smooth user experience by ensuring they can easily identify and process the information relevant to their scheduling tasks.
