Quadratus is a window design for Chanel's bag.

 

It is inspired by geometry. In this design, each unit is stretched to a different geometric shape based on squares. Quadratus is Latin for square.

​

The color scheme for the design is complementary. Red-orange and blue-green creates a contrast between energetic and calm, which represents two different attitudes. When people walk pass by the window, they will feel the changing of the emotion.
