Communication design is a way of using art, words, and images to create something that people can understand easily and quickly. It helps people understand messages or ideas quickly, which could be things like a book cover, a poster, or a website. Designers use different colors to help people know what the message is about, different fonts or styles of writing to show how important or interesting something is, and images or illustrations that help to explain the message. Communication design helps to make the information easier to understand.
