Karla has founded the Oh! Quadro Pop Up Gallery to encourage the art dialogue between the cultures.

After numerous travels between her home country of Brazil and her chosen home country Germany, she came to the realization that the intercultural exchange can be a way to show the alleged differences in similarities and to connect them together. Visual art is a way of initiating and maintaining this dialogue.
As a student she lived for three years with a family of art collectors in Cologne. "Art sharpens the senses" was intensively lived there. This has strongly influenced her and to this day she is fascinated by it.

Immigration has shaped our cultural history. The development of entire regions was influenced by people of different backgrounds, their arts, ideas and views and the "Intercultural dialogue can be a way of discovering and linking together supposed differences and similarities," says Karla Köster of the Oh! Quadro Pop Up Gallery.
