every floor in the building has two levels. the entrance is in one and the exit is through the other. the are also four elevators two in each level A, B and C, D. in order to make things more clear to visitors we decided to spilt the building in to two colors- Red and Turquoise. this colors help navigate and make the complex more vibrant and welcoming.other small generic signs that are painted black to fit with the black doors of the hangers, the signs directing the exits got yellow graphics.
