Red Orange Yellow Blue and Green [redorangeyellowblueandgreen.com] by Linden Tibbets is a simple, interpretative interface that reveals all the historical changes in the United States Homeland Security Advisory System.

This month, Homeland Security Secretary Janet Napolitano is set to announce the findings of a 17-person panel assigned the task of deciding the future of the current color-coded terror alert system. The aim of this project is to design a compelling experience around a relatively simple data set: the number of days that have passed after each change to the Homeland Security Advisory System. The system includes some subtle design cues, including the choice in proportion, color, typeface and as well as an experiment with systematic typographic deconstruction to aid relational awareness as the user opens each individual change.
