The entire system was inspired by the rich visual history of Greece, one of the
birthplaces of art. The concept of the Golden Ratio, first studied by ancient Greek
mathematicians, was used as the base grid for many visual elements. This ratio
appears frequently in nature and was used to design the buildings in ancient
Greece.
The route lines are strictly at 90-degree angles, to mimic the symmetrical
buildings of Greece. However, rounded corners were added to make the design
friendlier. Each transit stop is inspired by a bird’s eye view of different Greek
columns. The square is the base while the inside circle is the column.
The color palette was inspired by the colors of the Mediterranean landscape.
Though Athens is a landlocked city, the goal was to design a system that felt free
and open, like the endless sea.
