It was especially known for being the "Hippie Cola" because of the focus of the harmful effects the color additive could have on children and the boycott of multinational brands.

This was followed up with a variety of sodas without artificial coloring.[13] Today many organic colas are available in Denmark, but, for nostalgic reasons, clear cola has still maintained its popularity to a certain degree.[14]
