This forty-sixth issue of the electronic review of the iriv celebrates the twenty years of our electronic journal (2004-2024). They are dedicated to the rainbow illustrated by six antique statues that evoke the five Olympic rings (blue, red, yellow, green, etc.) on the occasion of the Paris 2024 Olympic Games. The colors of the rainbow can symbolize human «storytellings». The world is not black and white, unlike the narrative of social networks. The culture of «clash», or of «battle», without nuance or subtlety, contaminates the communication between human beings by creating sterile quarrels and epidermal reactions. Fragmenting opinions rather than building bridges. We may not agree without personally attacking or yelling at each other. That reason trumps often negative emotions. The editorial article evokes the difficult transition to adulthood «over the rainbow» which can take the form of a new start. The educational article sees the rainbow as a symbol of diversity at school. The associative article declines its symbolism to exile and the reasons to exile. The European article considers the many connections, musical, literary, of the rainbow. The expert article addresses the many facets of associative, trade union, political and citizen engagement. The last article offers the testimony of a young Polish citizen who became a European citizen with the entry of Poland into the European Union in 2004, during the most decisive enlargement for Europe which could have chosen as a banner a rainbow of Nations.
