Yellow in Catalonia Streets

In Catalonia, the yellow colorant yellow ribbons has taken to the streets. And my conscience as a street photographer takes me to photograph everything yellow I see on the streets of Barcelona. The yellow symbolizes the Catalan people's desire for freedom for their political prisoners, unjustly imprisoned for having fulfilled their democratic work: to make what their voters asked them to do. When the prisoners will be free, i want to publish a book with my yellow pictures.
