Graphic designers aim to share information in the most creative and direct ways possible. Designers of the stop sign created a universal meaning for the color red by changing the stop sign’s color—which was originally yellow—to red, matching stoplights. Many graphic designers include a memorable typeface in designs—like Coca-Cola’s script logo, which has remained the same since it was created in the 1880s. Designers have a lot of competition for viewers’ attention. The design team behind Apple’s iPod advertising campaign used bright backgrounds and expressive silhouettes to create a captivating billboard. Great graphic designers understand how to appeal to their target audiences. For example, designers created the pizza emoji for friends to use in casual messages with one another.
