This is a precedent for the scale of Europe and a great excuse to talk loudly about Silesia and Katowice.
In one place, on a postindustrial coal mine area, Katowice are creating a public space - parks and gardens, squares and buildings for culture, education and entertainment.
Such a big place need an identity that will link and differ all the institution at the same time. That's why the identity was decided to be polymorphic, elastic and dynamic.
The project consist of a logo built on a triangle, isometric grid (it firstly came from a hexagon form - well known symbol of coal). I divided the area to five sections: section of music, section of dance, section of art, section of meetings and section of spectacles. Each part has its own color. The colors of logo depends on how many events take place in each section (it will be counted in percents by an application - f.i if there will be only music events - the logo will be only in one color).
and examples of use.
