Graphics, Illustration and Visual Communication Design The Cairo Citadel Corporate Identity by Rana Galal The Cairo Citadel is a corporate identity created for a historic site in Egypt. The identity is built on the theme of contrast, reflected in the slogan City of Contrast. Black and white are the primary colors, and a secondary color refers to a historic event that took place inside the citadel. The bilingual logo is set in a block form that can be split into two rectangles placed opposite each other, suggesting cultural change. Helvetica Neue was chosen as the main typeface for its simple geometric forms. A signage system was later developed with the same concept.
