Here is a great example of an Infographic (Informative Design).
The concept is very simple, and keeps the viewer's focus on the facts. The simplicity is also reflected in the color scheme: black, white, blue, and green. These colors seem to turn the viewer's thoughts more easily to night and sleep, and are good choices.
Most importantly, the information is the focus, and is very relevant and useful.
